FCA-125 SERIES Tyco Electronics Mid-Range Military/Aerospace Relays 25 AMPERES, SPDT HERMETICALLY SEALED ALL WELDED CONSTRUCTION BALANCED FORCE PERMANENT MAGNET DRIVE CONTACTS: SILVER CADMIUM OXIDE WITH GOLD PLATING COILS FOR DC, 50 TO 400Hz AND 400Hz AC WEIGHT 1.6 OUNCES MAX. (45.4 GRAMS) * Meets new spec MIL-PRF-83536/36 and MIL-PRF-83536/37 The Series FCA-125 relay is a polarized 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.
