Feature MIL-DTL-26482 SI qualification → Business Impact: regulatory compliance and proven interoperability across aerospace, defense, and industrial equipment; Application: high-reliability harnesses in harsh environments. The aluminium shell with cadmium plating provides lightweight, corrosion-resistant protection, enabling longer service life in corrosive or abrasive settings and reducing maintenance cycles in outdoor or factory-floor installations. Solder Cup contact delivery with a socket (female) configuration improves wire termination reliability and PCB/harness integration, translating to fewer field failures and faster technician turnaround during assembly. A straight backshell and 1/3 bayonet coupling offer rapid, secure mating with vibration resistance, decreasing rework and downtime in assembly and maintenance workflows. The 25-position layout supports dense signal/power needs, while the X orientation and 44 mm length simplify panel design and routing in compact control cabinets.

FAQs
Yes. The 85100A2025SX50 is designed as a square flange receptacle within the Souriau 851 family, featuring a straight backshell with X orientation and a 25-position layout. Mounting should follow the panel cutout specifications for a square flange receptacle, ensuring proper alignment of the 1/3 bayonet coupling and secure fastening to the host panel to maintain mating integrity under vibration.
MIL-DTL-26482 SI qualified connectors are built to tolerate high-vibration, wide temperature ranges, and environmental contaminants. The 85100A2025SX50 uses an aluminium shell with cadmium plating, solder cup contacts, and a straight backshell to ensure reliable mating, corrosion resistance, and stable electrical performance across demanding industrial and military applications.
Absolutely. The 25-position configuration, square flange receptacle design, and bayonet coupling are well-suited for high-density harnesses in aerospace, defense, and automated industrial equipment. Its compatibility with the 851 series and regulatory compliance supports robust signal and power connections in both control cabinets and field-deployed systems.
This connector carries MIL-DTL-26482 SI qualification for military-standard interchangeability and reliability, and it is REACH compliant for environmental safety. While CE and IP ratings are not specified in the provided data, the MIL standard and REACH compliance indicate strong regulatory alignment for many industrial and aerospace applications.
Expect durable performance in harsh environments due to the aluminium shell and cadmium plating, which reduce corrosion wear. The solder cup contacts provide solid, field-terminable wiring, lowering maintenance time. The 1/3 bayonet coupling and straight backshell enable quicker mating/demating cycles, contributing to lower maintenance costs and improved uptime over the connector’s lifecycle.
