FAQs
The 85100E1832SZ50 is a square flange receptacle designed for panel mounting with a backnut. It supports a Z orientation and a 32-position layout, matching standard MIL-DTL-26482 square-flange footprints. When installing, ensure the panel cutout accommodates the 33.7 mm width/height, use the backnut to secure the housing, and align the 1/3 bayonet coupling for reliable mating.
This receptacle delivers 32 solder cup contacts in a socket (female) configuration, pre-loaded for quick assembly. It uses 1/3 bayonet coupling for mating, with cadmium plating and an aluminium shell to support mechanical robustness. The arrangement supports standard MIL-DTL-26482 electrical performance within the -40 °C to 125 °C operating range.
Yes. The connector is MIL-DTL-26482 SI qualified, which meets stringent aerospace and defense reliability standards. It also carries REACH compliance for environmental responsibility. The aluminium shell and cadmium plating provide durability in demanding thermal and vibration environments common to avionics, military ground vehicles, and rugged automation equipment.
Typical use cases include aerospace avionics harnesses, military equipment wiring, and rugged industrial automation systems requiring high contact density. Its 32-contact layout, square flange mounting, and backnut/backshell mix enable compact, robust interconnects in control panels, instrument clusters, or avionics bays where space, vibration resistance, and regulatory compliance matter.
Delivered with connector, pre-loaded contacts, and a stable square-flange footprint reduces part mismatch and field servicing time. The 32-contact, robust cadmium-plated aluminium shell withstands harsh conditions, lowering replacement frequency. MIL-DTL-26482 SI qualification and REACH compliance streamline audits and procurement, contributing to lower lifecycle costs and higher system availability.
