Eaton 85100A2255PX50 Receptacle - SI qualified
Part Number: 85100A2255PX50
Quick Summary
The Eaton 85100A2255PX50 square flange receptacle provides MIL-DTL-26482 SI qualified connectivity for rugged equipment. Engineers often struggle with corrosion, misalignment, and unreliable terminations in tight enclosures. This design uses cadmium plating, an aluminum shell, and a 55-contact layout to meet MIL-spec expectations. It is delivered with the connector, includes pin male solder cup contacts, and features straight backshell and X orientation to simplify installation in complex assemblies. For procurement teams, the combination of a compact 44 mm depth, 40 mm height, and 40 mm width reduces housing space demands while enabling consistent mating with Souriau 851 series interfaces in aerospace, industrial automation, and rugged field deployments.

MIL-DTL-26482 SI qualification provides MIL-spec reliability in demanding environments, reducing field failures and maintenance costs for aerospace and harsh-industrial equipment. The 55-contact configuration supports high-density signal and power in a single connector, improving harness simplification and system reliability while enabling compact layouts in restricted enclosures. A 1/3 Bayonet coupling delivers fast, secure mating with predictable retention, minimizing downtime during assembly or field maintenance. Solder Cup contacts streamline terminations for PCBs and harnesses, lowering assembly time and increasing production throughput. The cadmium plating and aluminum shell deliver robust corrosion resistance and lightweight durability, extending service life in corrosive or high-vibration settings. With a straight backshell and X orientation, installation is straightforward in complex assemblies, reducing risk of misalignment and warranty issues.

FAQs
The 85100A2255PX50 is a square flange receptacle aligned with Souriau 851 series interfaces, offering a 55-contact footprint and a straight backshell. It delivers a ready-to-mate solution with connector orientation X and a 1/3 Bayonet coupling, reducing misalignment risk and enabling straightforward integration with compatible plugs and backshells in aerospace or rugged industrial systems.
This receptacle uses solder cup contacts for easy terminal attachment to harnesses or PCBs. The 55-contact layout supports dense wiring in constrained spaces, while cadmium plating on an aluminum shell improves durability in harsh environments. The delivered-with connector option minimizes additional procurement steps and speeds up installation timelines.
The 85100A2255PX50 is rated for -40 °C to 125 °C, covering extreme cold to hot environments typical of aerospace, defense, and heavy industrial installations. This wide range helps ensure consistent electrical performance and mechanical integrity across mission profiles without the need for frequency downgrades or special accommodations.
Yes. The 85100A2255PX50 carries MIL-DTL-26482 SI qualification, aligning with stringent MIL-spec reliability requirements. Its cadmium plating and aluminum shell are designed for rugged environments, while the REACH environmental consideration supports European regulatory expectations. This makes it appropriate for aerospace, defense, and other high-reliability sectors.
Plan for routine mating checks and inspection of contact integrity given solder cup terminations. The 55-position layout increases the importance of proper alignment to avoid bending or mismating. Wide-temperature operation and robust materials reduce corrosion and wear, but periodic inspection of the backshell and coupling interface is advised to preserve mating reliability and minimize warranty issues.
