Rotary / MDR Relays

Fairbanks Morse Defense and Ward Leonard MDR Rotary Relays deliver higher contact ratings than comparable relays used in military and heavy-industrial applications. By eliminating the need to connect contacts in series, the MDR design simplifies wiring and frees terminals for additional circuitry. Engineered to MIL-R-19523B (SH) standards and QPL tested for vibration, shock, and endurance, these relays provide unmatched reliability and performance, with over 500,000 proven operations.

Features:

  • Contact arrangements from 4PDT to 12PDT

  • Increased contact ratings without the need for series connections

  • Standard and low-noise models available

  • Backwards compatible with relays from other manufacturers

  • High-reliability design for mission-critical environments

Recommended Uses:

  • Naval and defence electrical systems

  • Heavy-industrial control applications

  • High-current, high-reliability switching needs

  • Environments requiring vibration- and shock-tested components
