FAQs
Yes. The 85100A1811PY50 uses a 1/3 bayonet coupling with a square flange receptacle design, providing secure, vibration-resistant mating. It is delivered with a connector and oriented for ease of harness routing (Y orientation), making panel installation straightforward in tight spaces and reducing rework from misalignment during assembly.
This model features 11 solder cup contacts with male pins, an aluminum shell (size 18), cadmium plating, and a 41 mm length by 33.7 mm width/height footprint. It operates from -40 °C to 125 °C and is REACH compliant, aligning with stringent regulatory and field reliability requirements for aerospace, defense, and industrial automation.
Aerospace, defense, and rugged industrial automation benefit most. The MIL-DTL-26482 SI qualification, lightweight aluminum shell, corrosion-resistant cadmium plating, and robust 1/3 bayonet coupling deliver reliable performance under vibration, temperature extremes, and exposure to contaminants typical of aircraft, naval, and processing environments, while reducing maintenance and downtime.
Install with the straight adaptor and square flange mounting for a clean panel fit. The product comes with a connector and features solder cup contacts, enabling straightforward solder termination. The Y orientation supports efficient harness routing, and the 11-contact array ensures the right balance of signal density and manageability in compact panels.
The 85100A1811PY50 delivers high reliability in harsh environments, reducing field failures and maintenance costs. Its corrosion protection and wide operating temperature range minimize replacement cycles, while easy installation and secure mating reduce labor costs during build, upgrade, and service campaigns—providing a favorable total cost of ownership in demanding programs.
