RM672-300-312-9500

Overview

The AirBorn RM672-300-312-9501 is a rectangular board mount plug from the R Series, designed for MIL-DTL-55302 compliance. It features a plastic body with six rows and 300 positions at a 1.91 mm pitch. The connector utilizes through-hole termination with gold-plated beryllium copper contacts. Rated for 3 A current, it operates between -65 °C and +125 °C. The housing is constructed from Polyphenylene Sulfide (PPS). This right-angle plug includes mounting ears and guide pins for secure installation.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for rugged environments
• Utilizes Polyphenylene Sulfide housing for thermal stability
• Features gold-plated beryllium copper contacts for reliable conductivity
• Includes integrated guide pins for precise alignment during mating

Applications

• Military avionics systems requiring high-density interconnects
• Ruggedized electronic enclosures adhering to MIL standards
• Board-to-board connections in defense communication equipment

Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm termination type and pin configuration. Ensure compatibility with existing guide pin holes on the target PCB. Confirm that the gold plating specification meets the environmental requirements of the final assembly. Cross-reference the position count to avoid substitution errors within the R Series family.

Selection Notes

Select this model for applications requiring a six-row, right-angle board mount solution. The 1.91 mm pitch supports high-density routing. Verify that the through-hole tail length fits the board thickness constraints. Consider the PPS material properties for operating temperatures exceeding standard plastic limits. Ensure the 3 A rating per contact satisfies the circuit load requirements.

Part Context

This component belongs to the AirBorn R Series, a line of rectangular connectors known for durability. The series offers various row counts and termination styles. The RM672 prefix indicates a specific plug variant within the broader MIL-DTL-55302 ecosystem. These connectors are engineered for harsh conditions where vibration resistance is critical.

Replacement Considerations

Compatible substitutes include other MIL-DTL-55302 compliant plugs with identical 300-position, six-row configurations. Verify that alternative parts match the 1.91 mm pitch and right-angle orientation. Ensure the replacement maintains the same guide pin interface and mounting ear dimensions for mechanical interchangeability.
