Using the patented SKEDD technology, the Redfit IDC is available in 4- to 20-pin versions and is suitable for permanent use on PCBs as well as for temporary connections for programming and debugging purposes. The solderless reversible direct plug-in connectors can be manually mounted on the plated-through holes of the PCB, which eliminates the need for extra sockets and any related soldering processes. They require no mating plug, saving on yet another component and reducing assembly and process costs. Plastic guides on the underside of the housing are longer than the contacts, thus preventing short circuits on the board underneath. Different size thicknesses of the guiding pins provide reverse polarity protection during the simple, (and tool-free), process of plugging and unplugging of the SKEDD connector. Depending on the application, between 10 and 25 mating cycles are specified.

The plastic housing is made of halogen-free LCP (liquid crystal polymers) of flammability class UL94 V0. The specified operating temperature ranges from -25°C to +105°C. The contact material, a copper alloy, is gold-plated on the SKEDD site and tin-plated on the IDC. The SKEDD contacts on the dual row plug connector are offset with a 2.54 mm pitch. On the cable side, the AWG 28 ribbon cable is connected with a 1.27 mm pitch. Further technical features include a rated current of 1.0 A per pin, an operating voltage of 100 V, isolation resistance of over 1,000 MΩ, voltage stability of 500 Vac/min, and contact resistance of maximum 10 mΩ.
