FAQs
The 85100AC1626SY50 is designed as a square flange receptacle with a straight backshell and Y orientation, compatible with Souriau 851 series mating interfaces. It uses 1/3 bayonet coupling for quick engagement and solder cup contacts for reliable, serviceable connections in panel-mounted assemblies.
It provides 26 solder cup contacts in a 26-position cavity layout, aluminium shell size 16 with cadmium plating, operating temperature from -40 °C to 125 °C, and a straight backshell. Environmental consideration includes REACH compliance and MIL-DTL-26482 SI qualification for rugged, high-reliability interconnects.
Yes. The 85100AC1626SY50 belongs to the Souriau 851 series and is MIL-DTL-26482 SI qualified, designed for demanding environments with vibration, EMI considerations, and moisture exposure, making it well-suited for aerospace, military, and other mission-critical systems.
MIL-DTL-26482 SI qualification confirms performance in stringent conditions, and REACH compliance addresses chemical substance restrictions. Cadmium plating contributes to corrosion resistance where permitted, while the aluminium shell provides lightweight strength for high-reliability assembly designs.
The 85100AC1626SY50 enables high-density interconnects with 26 contacts in a compact form factor, reducing panel real estate and installation time. Cadmium plating and aluminium housing improve durability, lowering maintenance costs, while the 1/3 bayonet coupling speeds mating in field service and minimizes downtime.
