The TE Connectivity 747847-6 is a 37-position D-Sub receptacle from the AMPLIMITE HD-20 series, configured as a right-angle through-hole solder mount. It accepts the standard DC (C-shell) D-Sub plug with 4-40 screwlock retention on the mating face.
Board Retention and Mechanical Fit
The backset spacing of 0.318" (8.08mm) sets the distance from the PCB to the mounting flange — a dimension to check if the enclosure wall or panel has a tight clearance budget.
Ratings and Duty
The 125V rating is the working voltage for the signal pair — standard D-Sub creepage distances support this at the 0.108" pitch typical of the HD-20 layout.
