FAQs
The 85100A2232PW50 uses a straight backshell adaptor and 1/3 bayonet coupling to simplify mating in tight panel spaces. It provides a 32-contact layout with solder cup male contacts and a square flange receptacle geometry, accommodating a 44 mm depth, 40 mm height, and 40 mm width. Delivered with connector options streamline harness integration and minimize field wiring steps, making it suitable for complex control panels and rugged environments.
MIL-DTL-26482 SI qualification signifies proven performance under military specification standards, ensuring compatibility with high-vibration and EMI-prone applications. This improves reliability, reduces qualification risk for programs, and supports compliance with defense and aerospace procurement requirements. For engineers, it means a connector type that aligns with stringent test protocols while maintaining manufacturability and supply chain consistency.
This receptacle is ideal for aerospace and defense suites, rugged industrial automation panels, and heavy equipment where reliability and small footprint matter. With 32 contacts, cadmium plating, and an aluminium shell, it supports dense harnessing, fast installation, and dependable solder-cup terminations in mission-critical assemblies and automated systems exposed to harsh operating conditions.
The device operates from -40 °C to 125 °C, covering extreme cold to high-heat environments. It uses cadmium plating on an aluminium shell to enhance corrosion resistance, and its REACH compliance helps ensure regulatory compatibility across global markets. This combination makes the connector suitable for outdoor, military, and industrial installations where environmental stress is a concern.
Cadmium plating provides excellent corrosion resistance, especially in harsh or coastal environments, but requires adherence to handling and disposal regulations. Aluminium shells offer lightweight strength and good thermal performance. For lifecycle management, schedule periodic inspection of solder joints and harness interfaces, and consider cadmium hazard controls in maintenance workflows to ensure continued reliability and regulatory compliance.
