IDC D-sub Connectors

IDC (insulation displacement contact) D-sub connectors are a type of electrical connectorthat's designed to be connected to the conductor(s) of an insulated cable, most commonly a ribbon cable(a cable with many conducting wires running parallel to each other on the same flat plane).

Applications for IDC D-sub connectors

IDC D-sub connectors, attached to ribbon cables, are helpful in situations where you need to make a lot of connections without a big number of wires. They're commonly used in computer and electronic systems that require multiple data buses to link internal peripherals, such as disk drives to their drive controllers. They're also frequently used in industrial and telecom applications.

How does an IDC D-sub connector work?

With an IDC D-sub connector, there's no need for cable preparation – in other words, you don't need the strip the cables of their insulation before connecting. To connect the cable to the connector, there are sharpened blades (or contacts) on the connector that force through the insulation around the cable, making a secure connection.
