What Is D-Sub Cable Assembly?

D-sub cable assembly is a customized cable or wire assembly using D-subminiature connectors for secure signal, data, or power transmission. It features male or female D-shaped plugs with pins from 9 to 50, designed for specific electrical, mechanical, and environmental requirements.This structure helps prevent wrong mating direction, improves mechanical strength and provides better protection for signal transmission.

D-sub cable assemblies are commonly used for low-voltage signal transmission, RS232 serial communication, control wiring, data acquisition, industrial I/O connection and equipment-to-equipment communication. Compared with standard off-the-shelf cables, a custom D-sub cable assembly can better match the equipment layout, pin assignment, installation space, shielding requirement and working environment.
