FAQs
Installation begins with aligning the 85100A2232PZ50 on the panel using the square flange holes. Secure the unit with appropriate fasteners, then mate the straight adaptor and engage the 1/3 bayonet coupling until a positive click is felt. Connect the solder cup conductors to the mating harness, ensuring pin alignment with the 32-position layout. Verify continuity and insulation resistance before system energization.
Yes. The connector operates from -40 °C to 125 °C, making it suitable for extreme environments found in industrial drives, outdoor equipment, and aerospace applications. For best results, ensure proper sealing and mating alignment during assembly and verify that solder joints are strain-relieved to withstand thermal cycling.
Connector accessory option indicates it can be delivered with the mating connector included. When ordering, confirm whether the assembly package includes the backshell adaptor, alignment features, and any required seals. This can reduce integration time and ensure correct fitment in your enclosure or panel design.
The 85100A2232PZ50 features MIL-DTL-26482 SI qualification, which demonstrates military-grade durability. It also adopts cadmium plating with REACH compliance, addressing environmental and regulatory expectations for many industrial and defense programs. Always verify regional restrictions on cadmium use for your project and consider cadmium-free options if required.
Key specs include 32 contacts in a 32-position layout, aluminium shell size 22, 44 mm depth, 40 mm width and height, and a 1/3 bayonet coupling for secure mating. The lightweight 48 g weight and compact dimensions support space-constrained panels, reducing enclosure size and installation time, which can yield lower system weight and shorter ROI cycles.
