FAQs

The 85100E1811PY50 uses a square flange receptacle design with a backnut and straight backshell, aligning with common panel cutouts and installation practices. The 11-contact arrangement and 1/3 bayonet coupling provide consistent mating alignment and robust mechanical retention in typical aerospace and industrial enclosures.
Key specs include 11 solder cup contacts, pin (male) contact type, cadmium plating on an aluminium shell size 18, 32.7 mm length, 33.7 mm height and width, and a weight of 31.6 g. Operating temperature ranges from -40 °C to 125 °C, with a straight backshell and backnut configuration for secure installation.
Yes. It is MIL-DTL-26482 SI qualified, which aligns with stringent aerospace and defense procurement standards. The product is REACH compliant, supporting regulatory requirements for environmental safety in both aerospace and industrial automation applications.
Plan for a clear mating orientation using the Y connector orientation setting, and use the backnut with the straight backshell for secure mounting. The 1/3 bayonet coupling enables fast mating/demating while maintaining vibration resistance, which is important in dynamic industrial or aircraft environments.
The combination of 11 contact points, robust cadmium-plated aluminium shell, REACH compliance, and wide temperature range reduces field failures and maintenance intervals. Faster installation with secure bayonet coupling and a compact form factor also lowers labor costs and downtime in automated systems, delivering measurable lifecycle savings.
