When is a cable extension sensor (POSIWIRE) the right choice over magnetostrictive (POSICHRON) or magnetic scale (POSIMAG)?

Decision rule: measurement range, installation simplicity and budget. Choose POSIWIRE (cable extension) when: • Measurement range is above 250 mm up to 50,000 mm . • Sensor body is fixed and mechanical tolerance with the moving part is forgiving — wire tip attaches via a small screw. • Budget is critical — typically 40-60% cheaper than magnetostrictive. • Mobile machinery, hydraulic cylinder external monitoring, lifts, cranes, test rigs. Choose POSICHRON (magnetostrictive) when: • Wear-free, contactless is critical (high-cycle, millions of cycles). • Accuracy at the ±0.02 mm level is needed. • To be integrated inside the cylinder (rod or profile). • Higher initial cost is acceptable. Choose POSIMAG (magnetic scale) when: • Linear motion on a surface , measurement range up to 30 metres. • Contactless , clean room or hygienic environment. • 1 µm resolution is required. Rule of thumb: Mobile machinery + hydraulic cylinder + outdoor installation → POSIWIRE is the most common correct answer. In-CNC position → POSICHRON or POSIMAG.

Output selection: 0-10 V, 4-20 mA, potentiometer, SSI, CANopen — which suits which PLC/DCS?

Output selection is driven by the input card on your PLC/DCS . Potentiometer (R1K, 1 kΩ): • Raw analog resistance output. The PLC needs a dedicated potentiometer input card or bridge circuit. • Advantage: most economical, simple. Typical use: low-cost test rigs. 0-10 V Voltage: • Industry's most common analog standard. Standard PLC analog input card suffices. • Limit: cable length above 100 m can introduce voltage-drop measurement error. • Typical use: fixed installation, sensor within 100 m of control room. 4-20 mA Current (2-wire or 3-wire): • Industry's most robust analog option. Noise-immune up to 1000 m cable length . • 2-wire: single cable carries power and signal (simple). • 3-wire: separate power + signal lines (faster). • Typical use: long distance, noisy industry, mobile machinery. Programmable Analog (PMUV, PMUI): • Voltage or current output with user-programmable upper/lower limits. E.g., 100-1000 mm range mapped to 0-10 V. • Typical use: precision applications requiring measurement range adapted to output dynamic. SSI Digital (12/14/16 bit): • Synchronous Serial Interface — high-accuracy digital position transfer. Requires PLC SSI input card (Siemens, Allen-Bradley, ABB offer standard options). • Advantage: no noise at all, resolution 16 bit = 65,536 steps. • Typical use: high-end CNC, robotics, presses. CANopen and SAE J1939: • Automotive and mobile machinery standards. 10+ sensors on one bus. • Typical use: tractors, excavators, trucks, test vehicles. Decision table: Standard industry → 4-20 mA . Mobile machinery → CANopen/J1939 . High-end CNC → SSI . Economical test → Potentiometer .

How do I select the measurement range? WS10 (1250 mm), WS31/42 (2500-5000 mm), WS100M (50,000 mm) — what are the boundaries?

Within the POSIWIRE family, measurement range selection follows actual stroke + 10-15% reserve . Mini / OEM (75-1,250 mm): • WS1.1, WS1.2, WS2.1, WS7.0 — small cylinders, compact in-machine, OEM integration. • Typical use: instrument position feedback, small linear motion. Industrial standard (100-2,000 mm): • WS10, WS11, WS12, WS17KT, WS19KT — most factory hydraulic cylinders, small lifts, door positions. • WS10 is the class reference — 7 stroke options at 100/125/375/500/750/1000/1250 mm. Medium-long (1,250-5,000 mm): • WS31 (1250 mm) and WS42 (2500-5000 mm) — ultra-compact OEM. Mobile machinery, small cranes. • WS21, WS58C, WS60, WS61 — industrial medium-long stroke. • WS85 (2500-5000 mm) — robust housing medium-long. Long distance (5,000-50,000 mm): • WS100M is the only option — 10-50 metre stroke. Stainless steel housing, IP68/69K, 4.5-6.8 kg. • Typical use: tall lifts (50+ floors), long conveyors, large cranes, mining equipment. Rule of thumb: • Stroke • Stroke 500-2000 mm → industrial standard (WS10/11/12) • Stroke 2000-5000 mm → WS31/42 or WS85 • Stroke 5000+ mm → WS100M (only option) • Stroke 30+ metres → WS100M custom order or with auxiliary sensor.

What advantage does the POSIWIRE® WST model with integrated inclination sensor offer for mobile machinery?

POSIWIRE® WST (2019 innovation) — combines position and inclination measurement in one module. In mobile machinery and especially crane/telescopic boom applications, it halves installation, cabling and certification costs . Classic installation (2 separate sensors): • One POSIWIRE cable extension (measures boom length) • One POSITILT inclination sensor (measures boom angle) • 2 sensors + 2 mounts + 2 cables + 2 PLC analog inputs + 2 separate calibration documents. WST integrated installation: • 1 sensor provides both position and inclination. • 1 mount, 1 cable, 1 connector. • Position and inclination outputs share the same CANopen or SAE J1939 message — single-channel management on the PLC. • Simplified certification documentation. Typical benefits (field data): • Installation time: 50% reduction (1 sensor vs 2) • Cable cost: 40-50% reduction (1 multi-conductor vs 2 sensor cables) • PLC programming: position and inclination in the same block — load chart calculation is simplified • Maintenance: a single sensor replacement restores both signals at once 3 models: • WST21 : 1250-2500 mm position · MEMS integrated inclination · small telescopic booms • WST61 : 1000-2500 mm position · integrated inclination · standard crane booms • WST85 : 2500-5000 mm position · integrated inclination · long telescopic crane booms Rule of thumb: If a mobile machine needs both position and inclination measurement (typical requirement for load charts), always prefer WST over two separate sensors — provided the model's measurement range fits.

How is the measuring wire mounted? Field practice and common mistakes.

POSIWIRE installation looks simple but three details can go wrong: 1) Straight wire pull-out angle (most critical): The wire must be drawn parallel to the direction it exits the spool . If pulled at more than 30° angle : • Wire rubs against the spool guide and wears (life shortens). • Linearity deteriorates (±0.05% f.s. → ±0.5%). • Pull/return force becomes inconsistent. Solution: If straight pull is mechanically impossible, use a guide pulley or wheel — it provides a parallel exit at the spool point. 2) Wire-end fastening: The small ring on the wire end attaches to the moving part with an M4 screw. Don't over-tighten — if pinched at the ring, the wire stays bent and return force is impaired. Correct approach: attach so the ring can move freely, only prevent it from falling off. 3) Cable (wire itself) fatigue: POSIWIREs have typical cycle limits of 100,000-1,000,000 cycles (model dependent). In high-cycle applications (e.g., 30+ strokes per minute): • Wire breakage is the main failure mode. • Solution: prefer magnetostrictive (POSICHRON) for high-cycle applications — no wire, unlimited cycles. 4) Force balance (WS10 example, from ASM datasheet): • 100 mm range: 4.7 N pull-out force / 3.0 N minimum return force • 1250 mm range: 4.6 N / 2.4 N As wire extends, return force decreases — if a fast-returning moving part causes wire slack, the spool's "magnetic brake" option (ASM-patented since 1998) is required. Additional practice: The wire should not sit in oil, water or grease — stainless steel wire is durable, but dirt creates abrasion between wire and spool. Keep the panel side dry (IP65/IP67 sealing handles this).

IP protection levels: IP50, IP65, IP67, IP69K — which suits which environment?

The POSIWIRE family offers 5 different IP protection levels ; selection follows ambient conditions. IP50: • Dust protection only, no water. • WS1.x, WS2.1, WS7.x mini OEM models. • Use: inside enclosed panels or dry rooms. Integrated into OEM equipment. IP65: • Fully dust-tight, jet-water immune. • Industry standard (WS10, WS11, WS12, WS21, WS31, WS42) . • Use: factory interior, oily/wet environment, normal industry. • Note: WS10 is IP65 only with mating connector attached — exposed connector drops to IP50. IP67: • Submerged for 30 minutes at 1 m depth. • WS85, WS10SG/ZG stainless/galvanised models . • Use: outdoor, rain, oxidising liquid splash, food processing. IP68 / IP69K: • IP68: continuous submerged operation (model-dependent depth). • IP69K: high-pressure hot-water jet (food-processing wash-down standard, 80°C 100 bar). • WS100M (304 stainless steel) is IP68/IP69K. • Use: dairy/beverage/meat processing, ship decks, mining-sensitive environments. Decision table: • OEM in-device, enclosed → IP50 • Factory interior, oily/wet → IP65 • Outdoor, rain, corrosion → IP67 • Food processing, wash-down, ships → IP68/IP69K ATEX dust hazardous is a separate certification — only WS10EX and WS12EX are certified II 3D Ex tc IIIC T80°C. IP protection is high (IP65), but the key gain is Ex certification.

What are the rules for using WS10EX / WS12EX in ATEX dust hazardous areas?

The ATEX POSIWIRE series is certified for dust hazardous areas (Zone 20, 21, 22) — not gas environments (Zone 0/1/2). An important distinction. Certification details (WS10EX and WS12EX): • Classification: II 3D Ex tc IIIC T80°C Dc X • Meaning: - II 3D = Category 3, dust environment (base category for Zone 22, applicable in Zone 21) - Ex tc = "protection by enclosure" — sealed body, no dust ingress - IIIC = all dust types including conductive - T80°C = surface temperature does not exceed 80°C - Dc = Equipment Protection Level (Dust, level c) - X = tested with low impact energy (4 J) — extra protection needed where high impact risk exists Suitable zones: • Zone 22 (no explosive dust atmosphere in normal operation, may form briefly): WS10EX/WS12EX can be directly installed . • Zone 21 (may be present in normal operation): usable but mounting + documentation approval required. • Zone 20 (continuously present): WS10EX/WS12EX NOT SUITABLE — Zone 20 requires Ex ia or Ex tb-certified sensor. Standards: DIN EN 60079-0 (general) and DIN EN 60079-31 (dust protection). Installation rules: • Cable: standard 2 m PUR cable (connectorless). Any extension box must be Ex-certified for the zone . • Earthing: housing earthed at a single point (potential equalisation). • Maintenance: must occur when explosive atmosphere is absent (hot work permit). • Documentation: the sensor certificate must be kept in the plant's ATEX documentation file. Typical applications: grain silo position measurement, flour mills, coal mining auxiliary equipment, woodworking. POSIWIRE for gas hazardous (petrochemical): Special certification handled separately — IMB Electric engineering team coordinates the custom-order process with ASM.

How do warranty, calibration, and IMB Electric's regional support work?

Warranty: ASM Sensor offers a 2-year manufacturer warranty on all POSIWIRE models (specified in datasheets). Out-of-warranty cases: • Exceeding maximum cycle limit (wire fatigue — high-cycle misuse) • Physical damage (impact on cable, breakage) • Use outside datasheet limits (temperature, IP, ATEX) • Unauthorised opening or repair Calibration: POSIWIRE is an electromechanical sensor; typical calibration interval is 2-3 years . Annual check is recommended in accuracy-critical applications. For field verification: • Full wire extension (maximum stroke) and full retraction (0 position) signals are measured. • Must stay within ±0.10% f.s. (standard L10) or ±0.05% (premium L05). • IMB Electric provides accredited calibration services in Türkiye (TÜRKAK-scope). IMB Electric Regional Support: IMB Electric is listed for Türkiye on ASM Sensor's official global distribution network , with authorisation extending to Türkiye + the Middle East + North Africa + Western Asia . Regional services: • Stock delivery (İstanbul İkitelli OSB) • Fast quotation (24-48 hours) • Accredited calibration and repair service • Application-based engineering support — sensor selection, installation help, certification documentation • Local management of warranty processes • Turkish + English technical documentation • Field training (on request) Contact: info@imbelectric.com · +90 212 544 59 59 · imbelectric.com

What is POSIWIRE LR19? How does it differ from standard POSIWIRE, and why is it preferred for OEM applications?

LR19 is a special POSIWIRE variant — fundamentally different from standard POSIWIRE sensors: no internal encoder/signal-conditioner ELECTRONICS . LR19 is sold only as a mechanical cable-extension unit . The customer connects their own encoder (motor encoder, own design or supply) to LR19. Why Preferred? OEM (Original Equipment Manufacturer) integration: If a machine builder uses a common encoder standard (own supply), they want to combine that encoder with POSIWIRE's mechanical cable-extension system. Cost optimisation: Customers who supply their own encoder pay only for the mechanical housing + cable + spool. Special output protocol: If ASM's standard outputs are insufficient or the customer's specific control system requires a different signal. LR19 Accessories: WS-EXZENTER — Synchro flange, for non-ASM motor shaft connection WS-ADAPTER19 — Clamp flange, alternative clamp connection MK1-29-6-6 — Shaft coupling for clamp flange MK1-24-6-10 — Shaft coupling for synchro flange -BK option — "Encoder provided by customer and mounted by ASM" — ASM mounts the customer's encoder Typical LR19 Applications: OEM machine design (crane builder wants to use their standard encoder) Special motor + cable combination (elevator with integrated servo motor) Spare ASM mechanical housing (existing customer preserves their encoder, replaces only the worn mechanical part) Precision shaft position measurement + long range LR19 vs Standard POSIWIRE — Decision Table: Standard industrial application → Standard POSIWIRE (WS10/WS12/WS17/WS19 etc.) — pot/encoder included OEM machine production + own encoder → LR19 + adapter combination Special signal interface needed → LR19 (for custom output) Cost Impact: LR19 (mechanical only) is typically 30-50% more economical than standard POSIWIRE. However, customer's encoder cost is added — total cost depends on application.

Is it possible to change the output type of an existing POSIWIRE? (e.g., switching from 4-20mA to 0-10V)

Yes, it's possible. The signal conditioner inside POSIWIRE is a separate replaceable module. This can be used to change the output type of your existing sensor — without buying a new sensor. Available Signal Conditioner Modules: PP530 — Premium programmable signal conditioner PMUI — Programmable 4-20 mA output (zero/span adjustable) PMUV — Programmable 0-10 V output (zero/span adjustable) ADSI — Premium signal conditioner 420T — 4-20 mA 3-wire (transmitter) 420A — 4-20 mA 2-wire (current loop) 10V — 0-10 V output 1V / 5V / PM5V — 0-1 V or 0-5 V output Typical Replacement Scenarios: 4-20 mA → 0-10 V: Old PLC 4-20 mA input card replaced with new card supporting 0-10 V. Switch 420T module to 10V. 0-10 V → 4-20 mA: For long-distance signal transmission (>30 m, voltage signal weakens). 10V → 420T replacement. Standard → Programmable: For flexible calibration, PMUI or PMUV — user zero/span field-adjustable. Replacement Process: Customer reports current sensor model + serial number to IMB Electric. Target output type determined. Correct signal conditioner module sourced. Replacement performed at ASM-authorised service or IMB Electric workshop. CRITICAL: After module replacement, the sensor must be recalibrated . Linearity and reference points re-established at an accredited calibration lab (TÜRKAK accredited IMB Electric). Delivered with test and calibration certificate. Cost: Signal conditioner replacement is typically 20-30% of new sensor price (module cost + labour + calibration). Economical advantage if the sensor mechanics are still intact. Limitations: In pot-based POSIWIRE, the pot is mechanically coupled — signal conditioner replacement converts pot output to a different voltage/current signal, but pot resistance remains the same. In encoder-based POSIWIRE (IE series), encoder and signal conditioner can be replaced together. If the old sensor has mechanical wear (cable, spring), replacement isn't worthwhile — a new sensor makes more sense. IMB Electric Service: In Türkiye, we offer signal conditioner replacement + accredited calibration (TÜRKAK scope). Typical lead time 1-2 weeks.

I want to display POSIWIRE position directly on a panel without using a PLC — how do I do it?

Yes, you can display POSIWIRE position directly on a panel without PLC integration. PRODIS — ASM's universal panel meter, common to the entire sensor portfolio. PRODIS Variants: PD-ADC-24VDC — Analog sensor input (0-10 V / 0.5-4.5 V / 4-20 mA), 24 VDC supply. Suitable when POSIWIRE output is U2/U8/I1. PD-ADC-230VAC — Same as PD-ADC-24VDC but 230 VAC mains supply. Industry cabinet standard. PD-INC-24VDC-... — Incremental sensor input (TTL / RS422 / HTL). Suitable for POSIWIRE incremental encoder models. PRODIS Options: -230VAC — Add 230 VAC supply later -REL2 — 2 relay outputs (for position limit alarm, switching function) -DT — Desktop housing (for calibration lab or field test) Typical Use Cases: Control cabinet panel meter: POSIWIRE sensor cables via M12 to cabinet → PRODIS input → position value read on operator panel. PLC unnecessary. Limit alarm system: With PRODIS -REL2 option, when position exceeds a value, the relay triggers → warning lamp, alarm siren, motor stop. Field calibration test: PRODIS -DT (desktop) version as a reference reading device during sensor calibration. Advantages: NO PLC programming needed — just cable connection Same PRODIS for all ASM series — single-model inventory Compact panel meter — DIN 96×48 mm standard Low cost — much more economical than industrial PLC and HMI Stock delivery from Türkiye (İstanbul İkitelli OSB) Decision: If you only need to display position on a panel + simple alarm, PRODIS is sufficient and economical. Full industrial automation (data logging, multi-sensor coordination, recipes) requires PLC.

ASM GmbH Posiwire® Cable Extension Position Sensors

Linear position from 75 mm to 50,000 mm · ASM Germany · industry standard since 1979

The cable extension position sensor is the most widely used linear position measurement technology for hydraulic cylinders, mobile machinery, lifts and test rigs. The wire end attaches to the moving object via a small screw while the sensor body stays fixed; the object's motion is measured as wire being pulled from / returned to the spool. Installation is far easier than optical or magnetic scale sensors, mechanical tolerance is forgiving, and the working angle is wide.

The ASM POSIWIRE® family is extremely rich in measurement range and output interface: 25+ models covering 75 mm (WS1.1) to 50,000 mm (WS100M), with outputs including potentiometer, 0-10 V voltage, 4-20 mA current, programmable analog (PMUI/PMUV), SSI digital, CANopen, SAE J1939, IO-Link, and magnetic absolute encoder. IP protection spans IP50 to IP69K.

Key innovations: in 2018, POSIHALL® magnetic absolute encoder outputs were integrated into POSIWIRE; in 2019, POSIWIRE® WST — combination models with built-in MEMS inclination sensor (WST21, WST61, WST85) — were introduced. For ATEX dust hazardous areas, the WS10EX and WS12EX models are certified II 3D Ex tc IIIC T80°C.
