Mid-range relays for aircraft

15 August 2018 Switches, Relays & Keypads

TE Connectivity’s CII mid-range relays offer critical size and weight savings in aircraft applications. Their balanced force design provides the benefits of consistently high contact pressure, reduced bounce and less arching, helping lead to extended contact life. The relays vary in size from the compact 5 A package all the way up to a 50 A version in a 2,54 cm cube enclosure.

FC-325 Series relays are hermetically sealed devices designed for harsh inductive, motor and lamp load applications in aerospace, defence and marine markets. Configured as a 3PST/NO (DM), the double make/break contact design shares the load across two contact sets, resulting in less wear and tear on the relay. The relay’s all-welded design creates a reliable alternative to similar solder sealed relays in the market.

The Series FCA-210, FCA-410 and FCB-205 relays employ a polarised single-side stable design, where the flux from a permanent magnet provides the armature holding force in the deactivated state, and its flux path is switched and combined with the coil flux in the operated state. This results in appreciably increased contact pressure in both states over that of a spring return nonpolar design.

A variety of coil options are available which allow AC or DC control. Terminal styles include socket pins, solder pins and solder hooks. Each series comes with a variety of mounting options and all are qualified to MIL-PRF-6106 and MIL-PRF-83536.
