Compliant with MIL-DTL-26482 Series I standards, designed to withstand extreme shock, vibration, and temperature fluctuations for rugged environments.
Bayonet coupling enables quick, tool-free mating/unmating while ensuring connection integrity under mechanical stress.
IP67 rating and polychloroprene insulator prevent dust, moisture, and fluid ingress, suitable for outdoor or wet applications.
Gold-plated contacts minimize signal loss and ensure stable conductivity even after repeated mating cycles.
Five keyways for precise alignment eliminate incorrect mating, protecting both connector and downstream equipment.
