Tyco Electronics introduces hermetically sealed 50-amp relays

HARRISBURG, Pa. 4 Mar. 2009 The new FCA-150 and FCAC-150 series of relays from Tyco Electronics are designed for extreme environmental conditions regarding 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.

HARRISBURG, Pa. 4 Mar. 2009 The new FCA-150 and FCAC-150 series of relays from Tyco Electronics are designed for extreme environmental conditions regarding 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.

These new relays are targeted for applications such as avionics, missiles, aircraft, fuel pumps, and power distribution.

Rated for temperatures from -70 to +125 degrees Celsius 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.
