Feature → Business Impact → Application. The square flange receptacle design provides a stable, vibration-resistant mounting footprint, reducing assembly rework in machine enclosures and panels. This translates to lower field service costs and shorter downtime during maintenance. The 1/3 Bayonet coupling enhances mating ease and repeatable connections in confined spaces, delivering consistent electrical performance in robotics and automation systems. The 8 solder cup contacts deliver secure, durable interconnects for signal and power lines, supporting higher throughput and reduced contact resistance over the product lifetime. The aluminium shell offers strength-to-weight benefits, enabling easier handling during assembly and improved thermal performance in high-load applications. Cadmium plating provides corrosion resistance in challenging environments, contributing to longer service intervals and reduced replacement cycles. The delivered-with connector option simplifies stocking and installation, improving project planning and lifecycle management. The Y orientation and straight backshell support clean routing around tight machinery geometries, minimizing cabling complexity and risk of damage.

FAQs
To install the Eaton 85100E128PY50, start by ensuring the mating connector is aligned to the Y orientation and the straight backshell. Mount the square flange receptacle with the backnut securing it to the panel, then attach the mating plug using the 1/3 Bayonet coupling. Verify all eight solder cup contacts are fully seated and inspect for proper shielding and grounding continuity before system energization.
Yes, the 85100E128PY50 is part of the Souriau 851 series family and follows MIL-DTL-26482 specifications, ensuring cross-compatibility with other 851 series backnut, aluminium-shell receptacles. When integrating with other components, verify shell size, contact arrangement, and bayonet coupling to ensure a reliable, EMI-conscious connection across the harness.
Key specs include eight contacts in a square flange receptacle, pin male solder cup contacts, aluminium shell size 12, and a 1/3 bayonet coupling. Operating temperature ranges from -40 °C to 125 °C, with cadmium plating for corrosion resistance. The product is REACH compliant and delivered with connector, providing a ready-to-install solution for rugged industrial environments.
The 85100E128PY50 is MIL-DTL-26482 SI qualified, which ensures rugged, military-style interconnect performance. It also adheres to REACH environmental standards for chemical safety in manufacturing. While it is not an IP rating specification, its aluminium shell and cadmium plating are designed for demanding industrial settings where corrosion and mechanical stress are common concerns.
Installation is streamlined by the backnut mounting and the 1/3 Bayonet coupling, reducing tool time and alignment issues. The eight solder cup contacts provide reliable, durable connections that resist loosening under vibration, lowering maintenance frequency. The combination of a square flange design, delivered-with connector option, and robust materials translates to lower lifecycle costs and improved system uptime in automation projects.
