FAQs
The 85100E145SX50 uses a straight backshell and backnut configuration with a 1/3 bayonet coupling, designed for quick, reliable mating. Its X orientation aligns contact layout to ease wiring in dense panels, while the delivered connector option reduces assemblies needed in the field. Ideal for space-constrained installations in aerospace and industrial equipment.
It features five solder cup contacts in a five-cavity layout, cadmium plating on an aluminium shell, and a compact 32.7 mm length with 28.9 mm width and height. Operating temperature ranges from -40 °C to 125 °C, and the design is REACH compliant, supporting reliable performance in demanding environments.
Yes. The connector is MIL-DTL-26482 SI qualified, which is a key aerospace standard for secure, high-integrity electrical connections. Its aluminium shell, cadmium plating, and wide operating temperature range further support use in aircraft, defense, and other high-reliability systems.
The backnut provides a secure, weather-resistant mount, while the 1/3 bayonet coupling enables rapid mating without tools. This combination reduces installation time, simplifies maintenance, and minimizes the risk of improper mating, which translates to lower field failure rates in critical equipment.
