The TE Connectivity 1-745967-4 is a 25-position D-Sub receptacle from the AMPLIMITE HD-20 series, designed for standard-density signal interconnect in industrial control, instrumentation, and data-communication equipment.
The steel shell with tin plating provides EMI shielding typical of the D-sub form factor — the grounding indents in the shell mate with the connector face to bleed shield current before it reaches the signal pins. The female screwlock (4-40) on the receptacle side accepts the mating male screwlock from the plug, securing the pair without additional hardware.
