Eaton 85100AC2024PY50 MIL-DTL-26482 SI Qualified
Part Number: 85100AC2024PY50
Quick Summary
Eaton Souriau 851 series MIL-DTL-26482 SI qualified is a square flange receptacle designed for rugged aerospace and industrial interconnects. Engineers often struggle with mating reliability, compatible backshells, and space constraints in tight assemblies, and these issues can drive costly field failures. The 85100AC2024PY50 uses a straight backshell adaptor, cadmium plating, and a 24-contact configuration to deliver robust performance under harsh conditions. Its aluminium shell, 1/3 bayonet coupling, and pin male solder contacts ensure secure, vibration-tolerant connections across -40 to 125 C. The design also aligns with REACH environmental requirements, supporting compliant supply chains. For procurement teams, this lineage offers predictable interchangeability and reduced maintenance overhead in aerospace, industrial automation, and defense applications.

FAQs
The 85100AC2024PY50 is a square flange receptacle with a straight backshell adaptor and 24 contact positions, designed to align with standard Souriau 851 system backplanes. It uses a 1/3 bayonet coupling for rapid, vibration-resistant engagement and comes delivered with the connector, minimizing additional assembly steps. For compatibility, verify shell size 20, orientation Y, and cadmium-plated aluminium construction to ensure proper mating with your existing housings and harnesses.
Operating from -40 °C to 125 °C, the 85100AC2024PY50 is built for extreme environments typical of aerospace and defense applications. The aluminium shell provides robust mechanical strength, while cadmium plating ensures reliable electrical contact performance. Materials are REACH compliant, supporting global procurement programs and reducing regulatory risk.
Yes. This model belongs to the MIL-DTL-26482 family with SI qualification and a Souriau 851 series lineage, which are commonly specified for aerospace and defense interconnects. Its 24-contact configuration, 1/3 bayonet coupling, and square flange receptacle design support high-reliability avionics, control systems, and mission-critical harnesses in demanding environments.
The 85100AC2024PY50 is MIL-DTL-26482 SI qualified and uses REACH-compliant materials with cadmium plating. The aluminium shell and 24-contact configuration support regulatory and sourcing requirements for defense and aerospace programs, providing traceability and consistent performance under regulatory scrutiny.
Because the connector is delivered with the assembled unit and features a robust 1/3 bayonet mechanism, maintenance and field wiring time are reduced, cutting down on labor costs. The 24-contact density supports higher signal capacity per interconnect, improving system reliability and reducing downtime across capital equipment maintenance cycles in aerospace and automated manufacturing.
