MX Series — Heavy-Duty DC ContactorsMIL-R-6106 Standard

Military and heavy-duty silver-contact, hermetically sealed DC contactor family

GIGAVAC MX Series sealed DC Contactors are designed to meet MIL-R-6106 and are especially suited for military vehicles and heavy-duty applications. The hermetically sealed chamber shields the coil, contacts, and electronics from all outside environmental factors. The ceramic-to-metal weld provides a vibration-resistant, robust structure. Silver-plated contacts deliver low contact resistance and long life under high inrush conditions.

Pick token by token following the manufacturer's coding table; we'll generate the exact part number and open a tailored datasheet.

BELOW · LIVE PREVIEW

Coil codes vary by frame. S/T are low-power versions available only on 150 A & 200 A frames. K/L (AC) are available on the 150/200 A family except MX22. All coils include Internal Coil Suppression.

Applies only to the MXL14 and MXL15 latching models.

Auxiliary contact rating: 2A, 24VDC (Form A = SPST-NO and Form B = SPST-NC).

Applies only to the MXC15 and MXC16 CAN-Bus models.

TECHNICAL DIFFERENTIATORS

Why MX Series?

Superior Contact Construction

  • Contact build engineered for extreme currents

    No melting or welding even under sudden, high-current bursts.

  • Silver contacts deliver long service life

    Consistent performance under high inrush, motor starts and heavy duty.

Dual-Coil Design

  • Separate pick-up and hold coils

    Materially lower annual energy use in always-on applications.

  • Hermetic ceramic-insulated body + operation up to 200 °C

    Full environmental isolation — ideal for engine-bay and high-temperature use.

Military-Grade Certification

  • Designed to meet MIL-R-6106

    Officially qualified for military vehicles and heavy-duty environments.

  • cRUus and RoHS compliant

    International compliance, easy export and certification.

Heavy-Duty Current Performance

  • 150 A to 1000 A continuous contact current

    Single supplier across all 12 V – 48 V heavy-duty systems.

  • Inrush capability up to 6000 A

    Safe response to ESS make-current, motor inrush and heavy-inrush use.

Heavy-Duty Smart Variants

  • MXL (latching), MXSA (current sensing), MXSB (analog output), MXC (CAN-bus)

    BMS, current protection and digital comms — all from one family.

  • MXST (time-delay), MXSL (low-voltage protection), MXNC (Normally Closed)

    Dedicated models for every protection scenario.
