Solderless and direct plug-in connectors

New from Würth Elektronik eiSos is the REDFIT IDC SKEDD WR-WST family of solderless, space-saving and multi-pluggable connectors for signal transmission. The product range 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.
REDFIT IDC is a solderless, reversible, direct plug-in connector with SKEDD technology. It can be manually mounted on the plated through-holes of the PCB, which eliminates the need for extra sockets and any related soldering processes. It also requires no mating plug, therefore saving on yet another component and reducing assembly and process costs.
For miniaturised components in particular, the less space required and the lower the height needed for any pin headers and other connector components, the better. REDFIT IDC SKEDD connectors only take up room for the connector itself on the PCB – there is no need for extra space above the circuit board.
The SKEDD connector is attached to the ribbon cable via insulation displacement technology. The plastic guides on the underside of the housing are longer than the contacts, thus preventing short circuits on the board underneath. Different thicknesses of the guiding pins provide reverse polarity protection during the simple and tool-free process of plugging and unplugging the connector. Depending on the application, between 10 and 25 mating cycles are specified.
The plastic housing of the REDFIT IDC SKEDD WR-WST connector family 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 more than 1000 M, voltage stability of 500 V a.c./min, and contact resistance of 10 m maximum.
