FAQs
The 85100E1623PW50 uses a square flange receptacle with a backnut and straight backshell. It mates via a 1/3 bayonet coupling and is delivered with the connector, simplifying mounting to standard MIL-DTL-26482 panels. Ensure alignment with the W orientation and secure the backnut to achieve proper mechanical retention and electrical integrity.
This receptacle provides 23 pin (male) solder cup contacts in a 23-cavity layout. The solder cup contacts deliver solid, vibration-resistant joints suitable for harsh environments. With cadmium plating and an aluminium shell, the assembly offers robust corrosion resistance and long-term electrical performance under wide temperature swings.
Yes. MIL-DTL-26482 SI qualification, a high-density 23-cavity layout, backnut mounting, and the W-oriented contact arrangement make it well-suited for aerospace, defense, and rugged industrial harnessing where reliable mating and environmental resilience are critical.
Key standards include MIL-DTL-26482 SI qualification and REACH environmental compliance. Cadmium plating is noted in the specification; verify regional regulatory requirements for cadmium use in your program. The combination supports regulatory acceptance in demanding applications requiring MIL-grade interfaces and environmental stewardship.
The 1/3 bayonet coupling provides fast, tool-free mating and unmating, reducing maintenance time. The high-density 23-position layout minimizes panel complexity, while the ready-to-install configuration lowers installation time. Overall, this translates to lower downtime, faster field replacements, and improved system uptime in mission-critical environments.
