4.3-10 CONNECTOR
Small and reliable
With our new compact and easy to install connector series, we ensure that the increasing requirements within mobile communications are met. Despite the smaller size in comparison with the 7/16 connectors, excellent return loss and low passive intermodulation (PIM) values are achieved. Available in three versions: Screw, Hand-screw and Quick lock coupling.

Product Features
» One interface – 3 coupling variations
Screw / Hand-screw / Quick lock coupling
» Excellent passive intermodulation behaviour
Very low passive intermodulation
Independent of torque and coupling mechanism
» Premium RF performance independent of torque
Outstanding return and insertion loss
High screening efficiency
» Space and weight saving construction
40 % smaller than 7/16 series
25.4 mm compact flange size
Up to 60 % less weight compared to bigger RF series
» Excellent passive intermodulation behaviour
» Premium RF performance independent of torque
» Space and weight saving construction
» IP 68 watertight seal in longitudinal and transverse direction
Full radio and antenna protection in mated and unmated conditions with customized IP 68 solutions
Compliant with IEC 60529
