Eight contacts provide dense signal and power channels within a compact footprint, reducing harness complexity and improving mating reliability in tight equipment enclosures. This configuration translates to shorter assembly times, lower wiring errors, and easier field upgrades for control panels, robotics modules, and portable equipment. 1/3 bayonet coupling delivers fast, secure mating with minimal torque, cutting installation time in the field and on production lines. In demanding environments, this translates to higher uptime and simpler tool-less panel assembly for cabinet integrations in automation and aerospace applications. Cadmium plating offers corrosion resistance and electrical reliability in challenging environments, while the aluminium shell keeps weight down without compromising strength for durable field use. The backnut paired with a straight backshell orientation simplifies panel mounting and cable routing in restricted spaces. Solder Cup contacts enable straightforward, repeatable terminations and easier automated soldering processes, supporting consistent joint integrity across production runs. Delivered with connector and 8-contact configuration, this receptacle is well-suited for square flange panel mounting, enabling rapid installation and straightforward maintenance in control systems and rugged automation setups. Operating temperature from -40 °C to 125 °C ensures reliable performance in extreme conditions, and REACH compliance reinforces environmental responsibility across lifecycle stages. The combination of a compact shell size, robust 851-series design, and true MIL-grade construction makes this receptacle a dependable choice for high-availability automation, robotics, and defense-related equipment.

FAQs
For panel installation, align the receptacle with the mounting hole pattern and secure it using the backnut while ensuring the straight backshell orientation is correct for your panel cutout. The 1/3 bayonet coupling allows quick mating with the corresponding plug, and delivering with connector simplifies initial wiring. Verify the contact side is Socket (Female) and use solder cup terminations for a robust, vibration-resistant joint.
Key specifications include MIL-DTL-26482 SI qualification, eight contacts, solder cup contact type, aluminium shell, cadmium plating, and a shell size of 12. The operating temperature range is -40 °C to 125 °C, with REACH environmental compliance. These factors collectively ensure MIL-grade reliability, environmental protection, and system-level integrity in harsh environments.
Yes. The product specifications indicate REACH environmental compliance, which supports use in environments with strict chemical disclosure and emission controls. Combined with cadmium plating and aluminium shell, this receptacle maintains performance while addressing environmental and regulatory expectations in many industrial and aerospace settings.
The 85100E128SX50 is a receptacle designed to pair with the corresponding Souriau 851-series plug or mating connector. Ensure proper alignment of the X orientation and use the 1/3 bayonet coupling for secure engagement. Confirm that the plug side uses compatible solder-c cup contacts and that the panel mounting supports the square flange configuration for reliable locked mating.
Plan for periodic inspection of solder joints for signs of wear or corrosion, particularly in high-vibration environments. Cadmium plating provides corrosion resistance, but verify any cadmium-restriction requirements in your industry. The solid aluminium shell and backnut design offer durability and reuse potential, contributing to lower lifecycle maintenance and extended uptime for automation and control systems.
