描述：The 45107E18-11S50 from Amphenol is 451 series, MIL-DTL-26482 series I equivalent jam nut receptacle with 11 contacts. The 451 series miniature cylindrical connectors offer high density contact arrangements in a circular shell with salt spray exposure of 48hour, 500hour. These connectors have 5 key/keyway polarization with 3 point bayonet lock coupling for positive mating with no chance of cross plugging. Spring tension provided by a wave washer in the coupling nut ensures maintenance of interfacial seal between mating halves. Both the insert and main joint gasket are moulded from resilient neoprene insulator. These connectors are designed for harsh environments and have well-proven electrical capability to withstand extreme shock, exposure and vibration. The high reliability performance makes 451 series ideal for environmental sealing or pressurized applications. . Quick disconnect bayonet coupling for rapid mating and unmating .
