RM222-090-202-5500

Headers, Receptacles, Female Sockets Overview

The RM222-090-202-5500 is a rectangular MIL Spec connector from the AirBorn R Series, manufactured by Molex. It functions as a board mount receptacle with a vertical orientation and plastic body. The component features a dual row configuration providing 90 positions with a 1.91 mm pitch. Termination is achieved via through-hole soldering using tin/lead alloy. The contacts are female sockets plated with gold, constructed from beryllium copper and brass. Rated for 750 V and 3 A, it operates within a temperature range of -65 C to +125 C. The housing utilizes Polyphenylene Sulfide (PPS) and complies with MIL-DTL-55302 standards.
