RM452-196-321-9522

Headers, Male Pins Overview

The RM452-196-321-9522 is a rectangular MIL Spec connector from the AirBorn R Series, manufactured by Molex. It is a board mount plug with a right-angle orientation and plastic body. The component features 4 rows and supports 196 circuits with a 0.075-inch (1.91 mm) pitch. It includes mounting ears and utilizes through-hole termination. The contacts are gold-plated beryllium copper sockets rated for 3 A at 750 V. Operating temperatures range from -65 °C to +125 °C. The housing is constructed from Polyphenylene Sulfide (PPS).

Headers, Male Pins Feature Summary

• Complies with MIL-DTL-55302 military specifications for high-reliability applications.
• Features a right-angle board mount design with integrated mounting ears for secure installation.
• Utilizes gold-plated beryllium copper contacts for enhanced conductivity and corrosion resistance.

Headers, Male Pins Applications

• Aerospace avionics systems
• Military communication equipment
• Radar and navigation subsystems

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required polarization and termination specifications. Confirm that the gold plating thickness meets project requirements. Check for any recent Product Change Notifications (PCNs) affecting material composition or manufacturing location. Ensure the right-angle configuration aligns with the mechanical layout constraints of the target printed circuit board assembly.

Headers, Male Pins Selection Notes

Select this component when a high-density interconnect solution is required for rigid board-to-board connections in harsh environments. The 1.91 mm pitch allows for significant signal density within a compact footprint. The right-angle form factor facilitates efficient spatial arrangement in constrained chassis designs. Verify that the 3 A current rating per contact satisfies the electrical load requirements of the application circuitry.

Headers, Male Pins Part Context

This part belongs to the AirBorn R Series, a family of rectangular connectors designed for demanding industrial and defense sectors. The series is characterized by its robust construction and adherence to strict military standards. The RM452 variant specifically denotes a plug configuration with four rows, distinguishing it from receptacle or single-row alternatives within the broader product line.

Headers, Male Pins Replacement Considerations

Direct replacements must match the MIL-DTL-55302 standard, 196 position count, 4-row configuration, and 1.91 mm pitch. Compatible substitutes include other manufacturers' rectangular MIL-spec plugs with identical pinout and mechanical dimensions. Cross-reference mating interface details to ensure proper engagement with corresponding receptacles.
