The Amphenol FCI DC37P065HTXLF is a 37-position D-sub plug, part of the D series, with male pins arranged in two rows. It uses a solder cup termination for field wiring or cable harness assembly, and the shell includes grounding indents and shielding for EMI control. Typical applications include serial data interfaces, industrial control cabling, and test equipment where a reliable, shielded 37-pin connection is needed.
The 300V voltage rating provides ample headroom for most signal and low-voltage power applications within the connector's shell size.
This plug mates with a standard 37-position D-sub receptacle (female) of the same shell size (DC, C). The solder cup termination accepts stranded or solid wire — strip, tin, and solder into the cup. No crimp tool is required, but the build-to-print needs the mating receptacle and a backshell (sold separately) to complete the assembly. The unthreaded flange means the plug relies on the receptacle's threaded inserts or a separate backshell with jackscrews for mechanical retention.
