The Rosenberger RPC-SL series are interchangeable port connector systems for use with test equipment where test ports are frequently mated and re-mated. Under such heavy usage, Rosenberger RPC-SL interchangeable port connectors allow the equipment/device interface to be fully protected from potential damage, avoiding the risk of costly repairs.

The RPC-SL port connector includes a panel mounting half and a sexless interface which features two spring-loaded butt contacts. This ensures no wear occurs during mating and eliminates the possibility of accidental damage from mismatching of connector halves. Furthermore, the interface between the panel mount and the adaptor is slotted, preventing the mating faces from rotating and possible damage.

The RPC-SL portfolio offers both 26.5 GHz and 40 GHz versions. While adaptors can be interchanged and are available in different connector series, the connector heads in these two ranges are not compatible and can only be used with their own system.

Test Cables with Interchangeable Connector Heads
Rosenberger offers a wide range of connector heads for test setups which often require other connector series, such as N, PC-7 or SMA. Due to the special cable interface, mounting of changeable connector heads is made very easy without any need for tools. Test cables can be readily adapted to the required connector types already available on the DUT (Device Under Test).
