FAQs
This square flange receptacle is designed for panel mounting with a backnut backshell. It arrives configured as a receptacle with 25 solder cup contacts and 1/3 Bayonet coupling, oriented N, and includes connector delivery. Suitable for standard enclosure cutouts and compatible with common backnut assemblies to ensure vibration resistance and reliable cabling in automation panels.
The 85100E2025P50 uses a 25-position layout with Pin (Male) contacts in a solder cup configuration. It mates with a corresponding Souriau 851 series receptacle in a 1/3 Bayonet coupling, Straight backhell, and Backnut option. The connector is delivered with a mateable connector and is designed for straightforward termination and quick field mating.
Yes. It is MIL-DTL-26482 SI qualified, cadmium-plated for corrosion resistance, and built with an aluminium shell to withstand demanding conditions. The operating range of -40 °C to 125 °C and REACH compliance further support reliability in aerospace, automotive, and industrial automation applications where exposure to vibration, temperature swings, and chemicals is a concern.
The connector adheres to MIL-DTL-26482, with SI qualification for high-integrity signaling. It is REACH compliant and features cadmium plating, aluminium shell construction, and a backnut backshell, ensuring regulatory alignment for many aerospace and industrial programs and reducing compliance risk in global supply chains.
The 25-contact layout minimizes panel space while maximizing channel density, enabling compact harness routing. Quick mating via 1/3 Bayonet coupling reduces installation time and maintenance. The backnut backshell configuration improves vibration resistance, and pre-delivered with connector simplifies wiring, contributing to lower total cost of ownership through fewer spare parts and faster field servicing.
