The TE Connectivity 5747877-3 is a jackscrew socket from the AMPLIMITE series — the threaded fastener that locks a D-sub connector pair together. It carries a 4-40 socket on one end and a 4-40 screw on the other, with a 0.185" length below the head. Designed for use with AMPLIMITE Series HDF and HDP connectors, it provides the mechanical retention that keeps the interface mated under cable strain and vibration.
Thread Size and Hardware Compatibility
The 4-40 thread is the standard UNC size for D-subminiature jackscrews. The socket end threads onto the mating screw on the plug side; the screw end threads into the receptacle housing. The 0.185" length below the head sets the standoff between the connector face and the panel or PCB.
