MIL-DTL-26482 SI qualification and square flange receptacle establish standardized interoperability, reducing procurement complexity and eliminating part-number proliferation. This drives lower lifecycle costs and faster program timelines, especially in aerospace and industrial machinery where certified interconnects are mandatory. The backnut backshell with straight orientation delivers vibration resistance and easier field maintenance, enabling quicker mate/demate cycles in the cockpit or on the factory floor. Eight pin contacts with Solder Cup terminations (Pin gender) provide reliable, low-resistance connections for power and signal paths, while cadmium plating and an aluminium shell offer robust environmental resilience and lightweight construction for agile assemblies. Operating temperature from -40 °C to 125 °C supports extreme conditions, expanding usable installations across climates and duty cycles. The 16-shell size, 32.7 mm length, and delivered-with-connector configuration simplify harness routing and reduce assembly steps, improving overall site productivity. Compatibility with the Souriau 851 series enhances inventory management and spare-part planning, while REACH compliance assures regulatory alignment and supply-chain confidence.

FAQs
The 85100E168PX50 is a square flange receptacle with a backnut backshell and straight orientation. It leverages 1/3 Bayonet coupling for quick mating and eight solder cup contacts. When integrating into an 851-series system, plan for the 16-shell size and ensure mating with compatible Souriau 851 series receptacles. Delivered with connector support reduces field assembly steps and helps align pin configurations with your harness design.
This receptacle operates from -40 °C to 125 °C, suitable for extreme environmental cycles. It features an aluminium shell with cadmium plating and uses male solder cup contacts. The backnut backshell and straight configuration complement vibration-prone installations, while the 16 shell size and eight-position cavity support reliable power and signal paths in demanding environments.
The connector is MIL-DTL-26482 SI qualified, offering aerospace-grade interconnect performance. It also lists REACH environmental compliance, ensuring regulatory alignment for substances and packaging. This combination supports long service life, regulatory assurance, and compatibility with defense and aviation programs that require strict certification and environmental standards.
Yes. The 85100E168PX50 is part of the Souriau 851 series and is designed for compatibility with common 851-series harnesses and square flange receptacles. Delivered-with-connector configuration simplifies procurement and reduces mismatches in pin count and cavity layout. Always verify shell size, contact count, and coupling type to maximize interchangeability and minimize rework.
Ideal for aerospace, defense, and heavy-industrial automation where reliability under vibration and temperature extremes is critical. The 8-pin, backnut-backed, 1/3 bayonet coupling design reduces maintenance downtime and replacement frequency. The combination of MIL-DTL-26482 SI qualification and REACH compliance supports regulatory readiness, while its compact size and delivered-with-connector option streamline harness design, installation time, and total cost of ownership.
