The TE Connectivity AMPLIMITE HD-20 1-747150-4 is a 9-position D-Sub receptacle with female sockets arranged in two rows. It terminates via through-hole solder pins to the PCB and mates with the standard DE-9 (E shell size) male plug.
Sizing the Connection: Current and Voltage
Rated 6A per contact at 125V, this receptacle carries signal-level and low-power loads — think I/O lines, serial interfaces, or control signals, not a bus bar.
Mounting and Mating Hardware
The mating-side female screwlock (4-40) is the standard retention for vibration-resistant D-sub connections; the jack-screws on the mating plug thread into this flange to prevent the pair from backing off under cable strain or machine vibration. Build-to-print needs both halves: this receptacle plus the mating DE-9 male plug with 4-40 male screwlocks.
