Rugged relay for harsh inductive loads
TE Connectivity has launched a range of relays built to handle higher capacity loads than most comparable mid-range relays on the market, offering a 35 Amps/28Vdc resistive load rating.

The CII FC-335 series is aimed at military, aerospace and defence applications to manage harsh inductive, motor and lamp loads. 

“What sets this relay apart from other similar devices on the market is its 35 Amp resistive rating for both 28 VDC and 115 VAC loads. Until TE released this product, the highest current rating available in this configuration was 25 Amps,” said Randy Biddix, product manager for CII relays at TE Connectivity. “This gives customers additional current switching headroom in their applications.”

TE’s CII FC-335 series relays are built in accordance with MIL-PRF-6106 to ensure they meet rigorous military standards for use in power distribution, fuel pumps, guidance and navigation systems, weapons systems, and ground support equipment. The relays are designed with double make contacts that share the load across two contact sets, which helps minimize wear and tear, prolong relay life and provide more stable performance. The all-welded construction also offers a more reliable alternative to similar solder-sealed relays.

These versatile relays are available in solder hook or terminal block configurations as well as 28 VDC and 115 VAC coils configurations. The main contacts are also suitable for use in 360-800 Hz variable frequency applications required by newer commercial and military aircraft.
