FAQs
Installation begins with selecting the mating Souriau plug from the same 851 series. Align the orientation as Y, mate the plug and receptacle, and rotate the 1/3 bayonet coupling to lock. The contacts are already loaded as solder cups for straightforward field terminations, and the straight backshell facilitates panel routing in tight spaces.
This receptacle provides 24 solder cup contacts in a 24-cavity configuration, with an aluminium shell (size 20) and cadmium plating. It accommodates a temperature range of -40 °C to 125 °C, uses a square flange receptacle with a straight backshell, and ships with a loaded contact delivery designed for reliable solder connections.
Yes. The MIL-DTL-26482 SI qualification is designed for aerospace and defense environments, and the cadmium-plated aluminium shell offers strong corrosion resistance. Its 24-position configuration, compact footprint, and 1/3 bayonet coupling support reliable performance in aircraft, military vehicles, and harsh industrial equipment.
The connector is MIL-DTL-26482 SI qualified and REACH compliant, which helps with regulatory reporting and supplier qualification. Cadmium plating is noted in its specifications, so plan for cadmium-related handling and environmental considerations in your procurement and maintenance processes.
The combination of a robust aluminium shell, cadmium plating for corrosion resistance, and a sealed, loaded solder cup contact design reduces maintenance frequency and field failure risks. The 1/3 bayonet mating and compact form factor also shorten assembly time, lower field labor costs, and improve overall lifecycle reliability in avionics and industrial systems.
