The TE Connectivity 1-5747301-4 is a 37-position D-Sub receptacle from the AMPLIMITE HD-20 series, designed for through-hole solder termination to a PCB. It carries 30.0µin gold-over-phosphor-bronze contacts rated 6A per circuit at 125V, with a UL94 V-0 polyester housing.
This receptacle mates with a standard AMPLIMITE HD-20 D-Sub plug (male pin) of the same shell size — 4 (DC, C) — and position count. The female screwlock (4-40) accepts a male screwlock or a standard 4-40 jack-screw on the plug side.
