The 2-1617805-8 is a non-latching relay from the FCA-150 series, featuring a polarized, single-side stable design that uses a permanent magnet for armature holding force, resulting in increased contact force. This relay has a 1 Form X (SPST-NO-DM) contact configuration rated for a 50 A resistive load at 28 VDC. Available coil options include 6, 12, and 28 VDC, with a version offering back EMF suppression for the 28 VDC coil. Designed to meet MIL-PRF-6106 requirements, this hermetically sealed relay is built to withstand demanding environmental conditions, including a temperature range of -70°C to +125°C and altitudes up to 300,000 feet, making it ideal for aerospace power distribution applications.
