FAQs

This receptacle uses a straight backshell adaptor and a 1/3 bayonet coupling, designed to snap securely into mating halves with minimal tool effort. Termination is via solder cup contacts on a 27-contact layout, and the aluminium CAD-plated shell keeps weight down while maintaining corrosion resistance. Ensure panel cutouts match shell size 20 for proper alignment.
Yes. It operates from -40 °C to 125 °C and features cadmium plating on an aluminium shell, along with REACH-compliant materials. This combination supports reliable performance in aerospace, defense, and outdoor industrial settings where temperature swings and exposure are common.
The 85100AC2027PX50 is ideal for aerospace harness assemblies, military equipment, and rugged automation systems. Its high-density 27-contact arrangement, secure 1/3 bayonet coupling, and straight backshell make it suitable for space-constrained panels and field-deployable assemblies requiring fast, repeatable mating.
Contacts are supplied as solder cup male pins, enabling straightforward field termination to conductors. The 27-contact configuration allows dense wiring, and the 53 mm length with a compact 36.9 mm footprint supports tight installations in control panels and equipment bays.
The body length is 53 mm, with a square flange profile of 36.9 mm in height and width. The assembled weight is approximately 49.8 g. These metrics help project planning for enclosure fitment, cable routing, and vibration performance in aerospace and industrial environments.
