FAQs
The 85100A1214SW50 is designed to mate with Souriau 851 family plugs and other MIL-DTL-26482 compliant connectors using a 1/3 bayonet coupling. Ensure the mating plug uses solder cup contacts and the W orientation to align with the receptacle’s keyed pattern and backshell configuration.
This receptacle provides fourteen contacts distributed across eight cavities, with socket (female) solder cup terminations. The configuration enables compact, high-density connections suitable for signal and low-power applications in aerospace, defense, and rugged industrial equipment.
Yes. The assembly is rated for operating temperatures from -40 °C to 125 °C and features cadmium plating on an aluminium shell for enhanced corrosion resistance, supporting reliable performance in harsh environments and fielded equipment exposed to vibration and contaminants.
The straight backshell adaptor simplifies routing and harness integration, while the 1/3 bayonet coupling provides fast, secure mating and un-mating. Plan for the W orientation and ensure panel cutouts and mounting hardware accommodate the 41 mm length and 26.5 mm width/height to avoid clearance issues.
Expect reduced maintenance costs due to high reliability and extended service life under vibration and temperature extremes. The robust aluminium shell, cadmium plating, and 851 series compatibility minimize spare parts variety, expedite procurement, and shorten field repair times, delivering lower total cost of ownership in defense, aerospace, and automated systems.
