Eaton 85100A2461PY50 Connector Receptacle - MIL-DTL-26482
Part Number: 85100A2461PY50
Quick Summary
Eaton 85100A2461PY50 is a MIL-DTL-26482 SI qualified square flange receptacle designed for rugged aerospace and industrial harnesses. In complex wiring installations, misalignment, time-consuming mating, and difficult access can drive downtime and escalation of costs. This connector carries MIL-DTL-26482 SI qualification, REACH environmental compliance, and cadmium plating, providing durability in harsh environments. The straight backshell adaptor and Y orientation deliver mounting flexibility, while 61 contacts support dense signal distribution—enabling higher channel counts in control panels and automation systems. Designed for aerospace and industrial automation environments, it supports quick, reliable mating thanks to its 1/3 bayonet coupling and solder cup male contacts for robust wiring. This combination reduces installation risk and helps ensure long service life in vibration-prone applications.

MIL-DTL-26482 SI qualification ensures consistent performance in shock, vibration, and extreme temperatures, translating to improved reliability, smoother qualification tests, and lower field failure risk in aerospace and heavy industry. The 61-contact layout with 1/3 bayonet coupling enables higher channel density and fast mating, reducing harness length and downtime while improving signal integrity and EMI/EMC resilience in compact panels. Cadmium plating on an aluminium shell delivers corrosion resistance with lightweight benefits, supporting long service life in damp or salt-air environments typical of outdoor automation and aircraft systems. The straight backshell adaptor and Y orientation simplify mounting in tight enclosures, with the delivered-with-connector configuration accelerating assembly and reducing mis-wiring risk. Operating from -40 to 125 °C expands applicability across factory floors, aircraft equipment, and harsh industrial environments, while solder cup contacts enhance robust field terminations and serviceability.

FAQs
Mounting begins by aligning the straight backshell adaptor with the panel cutout and inserting the receptacle. Engage the 1/3 bayonet coupling until seated, then route the cable via the Y orientation. The connector is delivered with the assembly, which speeds installation and minimizes misalignment. Verify panel thickness and mating face tolerance to ensure consistent engagement.
The 85100A2461PY50 provides 61 solder-cup contacts in a dense 61-position layout, with a 1/3 bayonet coupling for reliable mating under vibration. The aluminium shell uses cadmium plating for corrosion protection, and the assembly is rated for an operating range from -40 °C to 125 °C. The design supports high-channel density while maintaining signal integrity in harsh environments.
Yes. With MIL-DTL-26482 SI qualification and a square flange receptacle format, the 85100A2461PY50 is tailored for aerospace harnesses, defense equipment, and rugged industrial automation.
