851 Series (MIL-DTL-26482 qualified)


The Souriau-Sunbank 851 1/3 bayonet coupling series qualifies with the MIL-DTL-26482 H standard. Its primary use is in aeronautical and military applications. 851 connectors are ideal for applications with harsh environmental conditions. This is due to the high number of mating cycles (500 cycles) and corrosion resistance (500h salt spray). An audible click ensures a quick and proper mating through a 1/3 bayonet coupling system. This feature eliminates uncertain connections. This, most importantly, reduces installation time and labor. The 851 series is RoHS compliant and MIL-DTL-26482 H qualified. These 851 connectors offer a large range of layouts. They combine power supply and signal transmission in a unique solution. This ultimately reduces system complexity and installation costs.
