4.3-10 - superior performance at miniaturized install. space

IMS Connector Systems is an international technology company that is specialised in the development and manufacture of high-frequency connection technology.
Due to increasing efficiency requirements of mobile network equipments, the compact and easy to install 4.3-10 connector series was developed and is characterized by its space and weight saving construction and fulfill the miniaturization of mobile network elements, which gains more and more importance. Despite the space saving construction the connector series allows, independent of torque, excellent return loss and passive intermodulation (PIM) values. Thanks to a universal jack, there are three different coupling variations possible: Screw, Hand-screw and Quick lock coupling. Compliant with the standards of protection class IP68, IMS Connector Systems offers as well watertight 4.3-10 solutions for indoor and outdoor applications.
