RM242-050-212-5500

Headers, Receptacles, Female Sockets Overview

The RM242-050-212-5500 is a rectangular MIL-Spec connector from the AirBorn R Series, manufactured by Molex. It features 50 positions arranged in two rows with a 1.91 mm (0.075 inch) pitch. Designed for board mount installation, this straight receptacle utilizes through-hole termination with pre-tinned tin/lead alloy contacts. The socket contacts are gold-plated beryllium copper, housed in a polyphenylene sulfide (PPS) body. It operates within a temperature range of -65°C to +125°C and supports up to 3 A current and 750 V voltage.
