The TE Connectivity 5207952-3 is a jackscrew socket — a female screw-lock accessory for AMPLIMITE HD D-Sub connectors. It carries a 4-40 socket thread on the mating end and a 4-40 screw on the panel side, with 0.250" (6.35 mm) length below the head. This is the hardware that secures the D-Sub connector to the panel or mating half, preventing the connector from vibrating loose in industrial or field-service environments.
Thread Size and Compatibility
The 4-40 thread on both the socket and screw ends is the standard UNC thread for standard-density D-Sub connectors. This jackscrew is designed for use with AMPLIMITE Series HD D-Sub connectors — it threads into the female screw-lock insert on the connector body and accepts a mating 4-40 screw from the panel or mating plug. The 0.250" (6.35 mm) length below the head gives enough thread engagement for most standard D-Sub flange thicknesses without bottoming out.
