RM222-050-251-5570

Headers, Receptacles, Female Sockets Overview

The AirBorn RM222-050-251-5570 is a rectangular military specification connector from the R Series, manufactured by Molex / AirBorn. It is classified as a receptacle designed for board mount installation with a vertical orientation. The component features 50 positions arranged in two rows, utilizing female socket contacts. Termination is achieved through flexible flex-mount terminals rather than standard through-hole pins. The housing is constructed from plastic material, and the contacts are gold-plated to ensure reliable signal transmission. This part adheres to MIL-DTL-55302 standards, ensuring compatibility with rugged environmental requirements typical of defense and aerospace applications.

Headers, Receptacles, Female Sockets Feature Summary

• Flex-mount termination design allows for secure connection without rigid through-hole pins
• Gold-plated female socket contacts provide corrosion resistance and low contact resistance
• Vertical dual-row configuration supports high-density circuit routing on printed circuit boards
• Compliant with MIL-DTL-55302 military specifications for durability

Headers, Receptacles, Female Sockets Applications

• Ruggedized electronic systems requiring flexible interconnect solutions
• Aerospace and defense avionics modules
• Military communication equipment interfaces
• High-reliability industrial control panels

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific suffix 5570 corresponds to the flex-mount terminal style, as other suffixes in the RM222 series may indicate through-hole or IDC variants. Confirm that the 50-position count matches the system requirement, as this series offers various pin counts. Ensure the vertical mounting orientation fits within the mechanical envelope of the target assembly. Cross-reference the MIL-DTL-55302 compliance status with current manufacturer documentation to confirm active production status.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a non-rigid termination method is required to absorb stress or misalignment between mating connectors. The flex-mount feature distinguishes it from standard through-hole receptacles like the RM222-080-201-5570. Consider the 50-position capacity against available board space. Verify that the gold plating meets the specific conductivity and wear requirements of the application environment compared to tin or silver alternatives.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AirBorn R Series, a line of rectangular MIL-Spec connectors known for their rugged construction. The RM222 prefix typically denotes a receptacle form factor. While many parts in this series use through-hole termination, the specific designation for this model indicates a specialized flex-mount variant. It shares the general dimensional and electrical characteristics of the R Series but differs in its physical attachment mechanism to the PCB.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 50-position count, dual-row layout, and specifically the flex-mount termination style. Generic MIL-DTL-55302 replacements may not fit mechanically due to the unique flex-terminal geometry. Verify cross-reference data from official Molex/AirBorn channels before substituting.
