TE Connectivity (TE) is pleased to announce the release of its new CII FC-335 series relay. Designed to manage harsh inductive, motor and lamp loads, this high-performance relay offers a rugged means of power switching in a range of aerospace, defence and marine applications. TE’s new relays are built to handle higher capacity loads than most comparable mid-range relays on the market, offering a 35A/28VDC resistive load rating.

“What sets this relay apart from other similar devices on the market is its 35A resistive rating for both 28VDC and 115VAC loads. Until TE released this product, the highest current rating available in this configuration was 25A,” 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 minimise 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 and 115VAC coils configurations. The main contacts are also suitable for use in 360-800Hz variable frequency applications required by newer commercial and military aircraft.
