RM242-020-212-2900

Headers, Receptacles, Female Sockets Overview

The RM242-020-212-2900 is a rectangular MIL-Spec connector from the AirBorn R Series, manufactured by Molex. It features a 20-position, dual-row receptacle configuration with a 1.91 mm (0.075 inch) pitch. Designed for board mount installation, it utilizes through-hole termination with pre-tinned tin/lead alloy contacts and hex turning jacksets. The housing is constructed from Polyphenylene Sulfide (PPS), supporting an operating temperature range of -65°C to +125°C. Rated for 3 A current and 750 V voltage, it complies with MIL-DTL-55302 standards.
