IDC ConnectorInsulation-displacement contact (IDC) connectors are electrical connectors that feature contacts with sharpened blades. This design allows the connector contacts to be forced through the wire insulation to achieve electrical contact with the wire conductor. This eliminates the need to strip the conductor insulation prior to connecting. At Electro-Prep, we offer a wide range of ribbon cables and IDC connectors in various gauges, pin sizes, and centerlines that can be customized to your unique specifications. We also provide several testing options to prove the quality and safety of our IDC assemblies. 

What Are IDC Connectors?

IDC, also known as IPC (insulation piercing contact) connectors, are common electrical connectors designed to pierce through wire jackets to connect to the wire conductors of insulated cables. During the connection process, the IDC connector’s contacts are inserted through the wire insulation and into the wire conductor without stripping the insulation beforehand. A primary benefit of IDC connectors is that they offer a reliable and quick way of connecting to discrete wires and flat ribbon cables. 

Some of the most common applications for IDC connectors include monitoring and access control systems, computer systems, and transportation components.

Advantages of Using IDC Connectors

IDC connectors have many advantages. For example, they are easy to handle and can be used without the need for special tools. They also do not require soldering. Other advantages include:

  • Reduced assembly costs. It is much faster to populate IDC connectors compared to other types of connectors. This speed reduces overall assembly costs.
  • Efficiency. Pre-stripping of the wire’s insulation is not required, and dozens of wires can be processed at once. 
  • Reliable connections. IDC connectors often include strain relief mechanisms that clamp and hold the wire in place. This secure connection improves reliability and prevents damage from flexing and strain.
