IDC D-sub connector

IDC D-sub IDC flat cable D-sub connectors with stamped contacts provide a modular approach to electronic inter-connection.
Outstanding features of these IDC connectors are high contact reliability, long life and low contact resistance.


IDC D-sub 3
These standard IDC D-sub connectors have stamped contacts. IDC technology is a solderless connection method which remains very popular in the mass production of electronic equipment.

Soldering can have several disadvantages ~ it can create thermal stress, and pretty obviously requires solder to be applied in what can be a costly reflow manufacturing process

Blue Bullet C = Quality class 1 = 500 mating cycles


Insulation displacement contacts (IDCs) allow a ribbon cable to be forced onto sharp tines on the back of the contacts; this action pierces the insulation of all the wires simultaneously. This is a very quick means of assembly whether done by hand or automatically.The design these IDC dsub connectors offers a very reliable mass termination and cost effective approach to interconnecting PCBs, or wire-to-board applications.
