FAQs
The 85100AC1811PZ50 is designed as a square flange receptacle with a straight backshell adaptor and Z orientation, compatible with Souriau 851 series components. Ensure the mating plug aligns with the 1/3 bayonet coupling and that cadmium-plated aluminium shells are properly cleaned prior to assembly. Delivered with connector status indicates ready-to-terminate interfaces, which reduces field assembly time and risk of misalignment.
This receptacle uses Pin (Male) contacts with Solder Cup termination, accommodating 11 cavities. It operates from -40 °C to 125 °C, providing resilience in extreme environments. Such specs support avionics, motor drive, and military communications harnesses, delivering stable signal integrity and robust performance across environmental conditions encountered in aerospace and defense applications.
Yes. The 85100AC1811PZ50 features a 1/3 bayonet coupling, Z-oriented interface, and a square flange receptacle design that enhances secure mating under vibration. The aluminium shell and cadmium plating add structural integrity and corrosion resistance, while the compact 51 mm length and 11-cavity layout support reliable performance in space-constrained panels common to aerospace and defense deployments.
The connector is MIL-DTL-26482 SI qualified and REACH compliant, aligning with stringent military and environmental requirements. While CE/IP ratings are not specified in the data, MIL-DTL-26482 SI qualification ensures high-reliability performance in mission-critical systems. Contractors can leverage this to meet procurement standards, reduce risk during qualification testing, and simplify supplier audits.
With a weight of 40.8 g and a compact 51 mm length, the 85100AC1811PZ50 minimizes mass and space penalties in assemblies. Cadmium plating provides corrosion protection, potentially reducing maintenance cycles in harsh environments. The 11-cavity layout and Delivered with connector option streamline spares management and field servicing, contributing to lower lifecycle costs through improved reliability and faster repair times.
