FAQs

The 85100AC145SY50 is a square flange receptacle with five solder cup contacts arranged in a 5-position layout (shell size 14). It features a straight backshell adaptor, cadmium plating, and a Y-oriented connector design that supports a 1/3 bayonet coupling for secure mating in compact installations.
Yes. The 85100AC145SY50 is MIL-DTL-26482 SI qualified, ensuring compatibility with the MIL interconnect standard for rugged environments, and it is REACH compliant, aligning with global environmental and material usage regulations.
Best-suited applications include aerospace avionics interconnects, defense equipment, and harsh industrial automation systems. The 5-contact, cadmium-plated aluminium shell configuration provides robust electrical performance, corrosion resistance, and a lightweight profile ideal for space-constrained assemblies.
The 1/3 Bayonet coupling offers fast, secure mating with reliable retention, reducing assembly time and ensuring consistent electrical contact under vibration. This is especially valuable in field servicing, where quick, tool-free mating improves uptime and maintenance efficiency.
Plan for a straight backshell adaptor and Y orientation to align with your panel cutouts and mating connector. Ensure the aluminium shell and cadmium plating are compatible with your environmental exposure, and pair with the corresponding mating connector to preserve EMI performance and mechanical integrity in demanding environments.
