FAQs
The 85100E1832S50 is supplied as a complete connector with a backnut and square flange receptacle. It features socket (female) solder cup contacts and a 1/3 bayonet coupling for secure mating. The assembly is delivered with connector hardware optimized for quick installation and reliable field service in rugged environments, with orientation set to N.
Key specs include 32 contact positions across a 32-cavity layout, solder cup contacts, a backnut-backed square flange, aluminium shell size 18, and cadmium plating. The product measures 32.7 mm in depth and 33.7 mm in both height and width, weighing 36.9 g. Operating temperature ranges from -40 °C to 125 °C, with a straight backshell.
Yes. The connector is rated for -40 °C to 125 °C, supporting reliable operation in extreme climates and demanding industrial or aerospace environments. Cadmium plating on an aluminium shell provides corrosion protection, while the 1/3 bayonet coupling and backnut design maintain mating integrity under vibration.
The 85100E1832S50 carries MIL-DTL-26482 SI qualification and adheres to REACH environmental requirements. Cadmium plating is specified for corrosion protection, and the aluminium shell contributes to durability across temperature and duty cycles common in aerospace and rugged industrial applications.
Begin by aligning the receptacle with the mating half and the panel cutout, ensuring the orientation is correct (N). Slide the backnut onto the connector body and thread it to secure the housing against the panel. Insert the mate and twist the 1/3 bayonet coupling until a firm click is felt. Verify solder cup terminations and confirm proper engagement before powering.
