RM222-100-222-5500

Headers, Receptacles, Female Sockets Overview

The AirBorn RM222-100-222-5500 is a rectangular MIL-spec connector from the R Series, manufactured by Molex. It features a board mount receptacle design with 100 positions arranged in two rows. The component utilizes through-hole termination for secure PCB attachment and includes mounting ears for stability. Contacts are female sockets plated with gold to ensure reliable signal transmission. Constructed with beryllium copper and brass contacts within a polyphenylene sulfide (PPS) housing, it supports a current rating of 3 A and a voltage rating of 750 V. The unit operates between -65 C and +125 C with a 1.91 mm pitch.
