RM242-020-212-5500

Headers, Receptacles, Female Sockets Overview

The RM242-020-212-5500 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 dual rows of socket contacts with a 1.91 mm pitch and supports 20 circuits. Termination is achieved via through-hole mounting with a 0.140-inch tail length. Contacts are gold-plated beryllium copper and brass, rated for 3 A current and 750 V voltage. Operating temperatures range from -65 C to +125 C, and it complies with MIL-DTL-55302 standards.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the official Molex/AirBorn datasheet to ensure correct termination style and contact configuration. Confirm that the required pin count and row arrangement match the design specifications. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure compatibility with mating plug components within the same R Series family. Validate thermal ratings against the operational environment requirements.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a vertical, dual-row receptacle is required for MIL-DTL-55302 applications. Choose based on the 1.91 mm pitch requirement and 20-position capacity. Consider the gold plating for corrosion resistance in harsh environments. Verify that the through-hole termination method aligns with the PCB manufacturing capabilities. Ensure the PPS housing material meets the chemical and thermal resistance needs of the installation.
