REDFIT IDC is a solderless reversible direct plug-in connector with SKEDD technology and insulation displacement connection. The SKEDD contacts are plugged directly into the plated through-holes of a PCB. A complete part and a potential error source is eliminated. This results directly in higher process reliability, savings in space, material and process costs.

Behind the scenes: REDFIT IDC SKEDD Connector – Testing, production and in action


IDC for Quick and Easy Half Pitch Cable Connection

4-Way Contact Principle for Reliable Electrical Connection

Reverse Polarity Protection of Plastic Housing for Correct Assembling

Tool-Free Mounting for Easy Plug and Unplug Process

SKEDD Contact Requirements

Easy and Simple Plug-in Process

The precise design of the apex area keeps the SKEDD contact elastic to guarantee a low insertion force even for connectors with a high number of pins.

Vibration-Proof Connection

At the end of the insertion process the contact normal contact force is high enough to ensure that no interruption occurs due to mechanical stress.

Reversible Connection

The flexible fork-type arms of the SKEDD contact adapt in an elastic way to the plated through-hole to realize multiple mating cycles.

Fitting Accuracy

The flexibility of the SKEDD contacts balances the grid tolerances within the PCB production to ensure the optimal interaction of connector and PCB.
