RM222-090-222-5500

Headers, Receptacles, Female Sockets Overview

The RM222-090-222-5500 is a rectangular MIL-Spec connector from the AirBorn R Series, manufactured by Molex. It is classified as a board mount receptacle designed for vertical installation on printed circuit boards. The component features a dual-row configuration with 90 positions and utilizes a 1.91 mm (0.075 inch) pitch. Termination is achieved through a through-hole soldering method. The contacts are female sockets plated with gold to ensure reliable signal transmission. The housing is constructed from Polyphenylene Sulfide (PPS), supporting an operating temperature range of -65°C to +125°C. Rated at 3 A current and 750 V voltage, it complies with MIL-DTL-55302 standards.
