Which applications is the SPS series suitable for?

The right SPS series use case depends on switching voltage, continuous current, inrush current, coil supply, mounting orientation and environmental conditions. For critical projects, verify the model-table datasheet ratings against your actual load profile.

What should I check first when selecting a SPS model?

Start with system voltage and continuous current; then check break capacity, inrush rating, coil voltage, auxiliary contact needs and datasheet temperature limits. The configurator builds the order code according to the manufacturer code structure.

Do datasheet ratings and configurator codes refer to the same product?

Yes. The series table shows technical limits; the configurator turns coil, contact, terminal and option selections within the same model family into an order code. For quotation, send both the generated code and your application note.

Do you provide technical support and cross-reference checks for this series?

Yes. Share your existing part number, operating voltage, load type and environmental conditions, and we can review technically suitable alternatives within the same series or adjacent product families.

What information should I send for a quotation?

The generated part number, quantity, target delivery date, application type, system voltage/current and any datasheet revision are enough. The RFQ cart helps collect these details in one request.

Will this information appear the same after publishing?

Yes. The FAQ and related-insights blocks are part of the application code and appear with the same design on the published site.

DSTI SPS Series 1-Passage Rotary Union

Compact, lightweight single-passage rotary union for air/gas — 600 PSI, 500 RPM

DSTI SPS Series is a compact, lightweight, corrosion-resistant single-passage rotary union for transferring air or gas (pressurized or vacuum) from a stationary source to a rotating component. Stainless steel shaft, hardcoat anodized aluminum housing and proprietary sealing handle up to 600 PSI (40 BAR) and 500 RPM. Comes standard with male NPT shaft connection, female NPT housing connection and two tapped mounting holes on the housing end. Integrates directly with through-bore electrical slip rings so air + signal + power transfer through a single rotating unit. Used in Turkey on robotic end effectors, automatic assembly machines, rotary test rigs and packaging lines. IMB Electric provides technical support, fast quoting and custom modification engineering nationwide.
