FAQs
Mount the square flange receptacle in a panel cutout sized for shell size 18. From the outside, thread the backnut to secure the backshell, align the connector orientation to X, and engage the 1/3 bayonet coupling with the mating plug. The unit ships Delivered with connector, simplifying field installation and ensuring proper contact alignment and mating reliability.
This receptacle operates from -40 °C to 125 °C, suitable for extreme aerospace and defense environments. It uses Solder Cup contacts in a Socket (Female) configuration, providing robust, soldered connections. With 32 contacts in a 32-position layout, it supports dense wiring while maintaining consistent electrical performance and EMI/EMC integrity.
Yes. The 85100E1832SX50 is MIL-DTL-26482 SI qualified with REACH compliance, making it well-suited for aerospace and defense harnesses as well as demanding industrial applications. Cadmium plating offers corrosion resistance, while the backnut/backshell arrangement ensures secure mounting in constrained spaces. The 32-position design supports complex wiring without increasing footprint.
Key certifications include MIL-DTL-26482 SI qualification, which ensures compatibility with stringent MIL-spec requirements, and REACH environmental compliance for European supply chains. The aluminium shell and cadmium plating align with industry practices for durability and corrosion protection, while the 1/3 bayonet coupling provides proven vibration resistance in mission-critical systems.
Cadmium plating provides long-term corrosion resistance, reducing maintenance and replacement frequency in harsh environments. The 32-contact solder-cup interface enables reliable field rework and soldering, lowering lifecycle costs. Lightweight aluminium shell and straightforward backnut mounting shorten installation time, improving equipment uptime and overall return on investment for production and field deployments.
