Male D-SUB High Density Connector 15/26/44/62 Pin D-SUB Connector

D-type connectors most commonly consist of two and sometimes more parallel rows of connections. The connectors feature a D-format metal shell that provides mechanical strength and limited electromagnetic screening. When mated, the metal shells of the plug and socket make contact to enhance screening effectiveness.

Panel mounting connectors are typically secured using nuts with additional threading that allows the mating connector to be locked in place, preventing accidental disconnection. Free connectors can be equipped with backshells that provide either screening (when metal) or protection (when plastic), along with cable strain relief.

Standard D-SUB connectors with two rows of pins (9, 15, 25, and 37 way) feature pins spaced approximately 0.108 inch (2.74 mm) apart, with rows spaced 0.112 inch (2.84 mm) apart. Higher pin counts and increased density are achieved through additional rows of pins.
