Eaton 85100E1418PY50 Receptacle - MIL-DTL-26482 SI
Part Number: 85100E1418PY50
Quick Summary
The Eaton Souriau 85100E1418PY50 Receptacle is a MIL-DTL-26482 SI qualified square flange connector designed for harsh industrial and defense environments. In design and procurement discussions, engineers often struggle with misalignment, corrosion, and unreliable mating under vibration; this solution mitigates those risks with a backnut assembly, aluminum shell, and a precise 1/3 bayonet coupling. The product carries MIL-DTL-26482 SI qualification and REACH environmental compliance, supporting stringent reliability and regulatory needs in aerospace, industrial robotics, and rugged equipment. By combining robust mechanical design with solder cup contacts and Y-oriented wiring, it offers predictable mating performance, easy field installation, and long service life. For buyers, this translates to reduced downtime and lower life-cycle costs while meeting space and weight constraints.

FAQs
Installation requires aligning the 18-contact interface with the mating plug, securing the backnut for a rigid panel mount, and choosing the Y orientation to match wire routing. The compact 28.9 mm width/height and 32.7 mm depth fit tight panels, while the 1/3 bayonet coupling provides quick, reliable mating. Ensure aluminum shell size 14 is properly supported and that solder cup contacts are clean prior to insert.
Key specs include 18 solder cup contacts inside an aluminium shell size 14, backnut backshell, straight orientation, and a 1/3 bayonet coupling. The device operates from -40 °C to 125 °C, with cadmium plating and square flange receptacle design. Delivered with connector, it supports loaded contact delivery and a Y connector orientation for precise wiring layouts.
Yes, the 85100E1418PY50 is MIL-DTL-26482 SI qualified, ensuring robust performance under vibration and temperature extremes. It also adheres to REACH environmental standards, supporting regulatory compliance for chemical safety. The combination makes it suitable for aerospace, defense, and rugged industrial automation where reliability is critical.
The MIL-DTL-26482 SI qualification and corrosion-resistant cadmium plating contribute to extended service life and reduced maintenance in harsh settings. Quick mating via 1/3 bayonet coupling lowers field installation time, decreasing downtime during panel changes. Overall, expect lower life-cycle costs and improved uptime in mission-critical equipment through predictable performance.
The 1/3 bayonet coupling provides secure, vibration-resistant mating with fast engage/disengage cycles, while the backnut ensures solid panel retention. This pairing reduces the risk of loosening in dynamic applications and simplifies field servicing. Reliability is enhanced for systems exposed to shocks, vibrations, and temperature fluctuations typical in industrial and military environments.
