Two of the most frequently used types in this series are types B and C connectors with up to a maximum 96 contacts. PCB Connector Type R is available for special applications as an inverted model, which is laterally reversed in comparison to type C. This product family also includes half configurations, whose number of contacts are reduced by half. Straight and angled solder, hand solder and Wire Wrap are available for the connections. Apart from the possibility of screwing the connectors to the printed circuit board, it is also possible to use a PCB clip to fix and secure them in place.
