FAQs

The 85100AC82SX50 uses a 1/3 bayonet coupling for fast, secure mating. Align the connector orientation to X, align the square flange, and push to engage the bayonet lugs followed by a quarter-turn to lock. Use the delivered connector as a baseline assembly, ensuring solder-cup contacts are seated properly and the backshell aligns with the adaptor for a sealed fit.
This receptacle provides eight contacts with socket (female) solder cup delivery. It features a cadmium-plated aluminium shell and supports a wide operating range from -40 °C to 125 °C, making it suitable for demanding environments in aerospace and industrial equipment while preserving signal integrity and mechanical stability.
Yes. The part is MIL-DTL-26482 SI qualified, ensuring adherence to rigorous military specifications. It is REACH compliant, addressing environmental and regulatory concerns for components used in global supply chains, which helps with regulatory approvals and green procurement programs.
Aerospace and defense industries frequently require MIL-spec 851-series connectors, and this square flange receptacle is well-suited for those environments. It also finds value in industrial automation and rail applications where robust environmental resistance, compact form factor, and reliable mating under vibration are critical to uptime and safety.
The unit weighs about 12.7 g and has a compact footprint with 48 mm length and 21 × 21 mm cross-section. This lightweight, small form factor supports tighter enclosure layouts, easier cable routing, and reduced overall system weight, contributing to lower installation costs and simpler field retrofits.
