HARRISBURG, Pa. -- Dec. 22, 2008 -- The new FCA-150 and FCAC-150 series of relays from Tyco Electronics are designed to perform under the most demanding environmental conditions of temperature, altitude, shock, vibration, and salt spray. Meeting the requirements of Mil-R-6106, the hermetically sealed, non-latching relays offer a 50-A switching capability in a compact package only one cubic inch in size and weighing less than 90 grams. This compact package size offers considerable size and weight savings over other 50-amp devices on the market.

Rated for temperatures from -70° to +125°C and operation to 300,000 feet in high-vibration and high-shock environments, the FCA-150 and FCAC-150 series are available with optional diode for transient protection. The FCAC-150 series offers auxiliary contacts with single-pole, double-throw operation at 2 A. Excellent isolation is maintained between main and auxiliary contacts. All current paths are welded and free of mechanical fasteners for additional robustness.

A polarized, single-side stable design results in appreciably increased contact pressure in both states compared to that of a spring-return non-polar design. The relays are configured as single-pole, single-throw devices with normally open contacts. A choice of three coil voltages is available: 6, 12, and 28 VDC.
