Introduction
This 50-ohm RF connector has a compact 4.3-10 female interface with captivated center conductor. It is for semi-rigid and flexible coaxial cables with 0.250-inch (6.35 mm) outer diameter. The 4.3-10 coax connector matches cable types such as RG402, PE-SR402FL and equivalent specifications. The connector uses dual solder termination and fixed center contact construction to form permanent electrical connections. It mounts to base station cabinet panels, RRH/AAU enclosures, test jigs and indoor distribution panels for 4.3-10 female port integration.
Features
The 4.3-10 female interface has a compact multi-thread coupling. As an alternative to larger 7/16 DIN connectors for radio equipment, its compact size is suitable for equipment with limited installation space.
This 4.3-10 coax connector uses dual solder termination for inner and outer conductors. It provides a permanent electrical connection with 0.250-inch semi-rigid and flexible coaxial cables. Soldered connections reduce intermittent contact concerns seen with conventional crimp termination.
A mechanically locked female center contact sits within the connector body, with axial retention force rated no less than 27 N (6.1 lbs). This locking design limits contact movement or separation during assembly, mating and servicing.
Optimized for coaxial cables with a 0.250-inch outer diameter, the 4.3-10-K250-MH connector matches RG402, PE-SR402FL, PE-SR402FLJ, PE-SR402AL and equivalent cable types for RF test, measurement and telecom applications.
