Eaton 85100A83PX50 Receptacle - MIL-DTL-26482
Part Number: 85100A83PX50
Quick Summary
The Eaton Souriau 85100A83PX50 is a MIL-DTL-26482 SI qualified square flange receptacle. Engineers frequently battle mating reliability, tight spaces, vibration, and corrosion when integrating connectors into compact enclosures. MIL-DTL-26482 SI qualification and REACH compliance help meet aerospace and high-end industrial standards while ensuring regulatory alignment. The cadmium-plated aluminium shell, 41 mm length, 21 mm width, and straight backshell adaptor enable faster installation, easier panel cutouts, and durable, repeatable performance. Designed for three solder cup contacts in a 3-position layout with X orientation, it supports efficient harness routing and long service life in harsh environments.

FAQs
The 85100A83PX50 uses a straight backshell adaptor and a square flange receptacle design, with an X orientation and 41 mm length. It ships as a connector-equipped unit, reducing the need for additional parts. For panel integration, verify the 8-shell size and 21 mm width/height to ensure a precise cutout and straightforward harness routing.
This model operates from -40 °C to 125 °C, ensuring functionality across wide seasonal and industrial conditions. It is cadmium-plated on an aluminium shell and meets REACH regulatory expectations, which supports durability in vibration-heavy or outdoor environments where thermal cycling occurs.
Yes. It is MIL-DTL-26482 SI qualified and uses a three-contact, solder-cup configuration with 1/3 bayonet coupling, offering reliable mating in high-vibration settings. Its compact 41 mm length and lightweight aluminium shell make it suitable for constrained spaces in aerospace panels and automation equipment.
Cadmium plating provides corrosion resistance and durability, but its use is subject to regional regulatory restrictions. Confirm local RoHS/REACH requirements and aerospace/defense procurement policies before selection. If cadmium restrictions apply, discuss alternatives with the supplier or explore cadmium-free finishes that maintain compatibility with MIL-DTL-26482 interfaces.
The 1/3 bayonet coupling enables quick, secure mating with hands-on ease, reducing tool requirements and assembly time. With three solder cup contacts across three cavities, wiring harnesses can be streamlined, and future maintenance is simpler, since each contact path is clearly defined and easy to inspect during post-install checks.
