4 GHz Bandwidth with 500-Cycle Mating Life
The 1-1337442-0: The 500 mating cycles are double what a budget BNC typically delivers; the silver-plated center contact and brass body resist wear through repeated connects and disconnects in a patch panel or field-test scenario.
Termination: Solder Center, Crimp Shield
Center contact is solder-terminated — a clean joint into the female socket pin. The shield termination is a crimp, using the supplied ferrule over the braid. The cable group is specific: RG-58C and 141A. The ferrule and center-contact bore are sized for these two 50 Ohm coax types; a different cable diameter means the crimp won't grip correctly and the impedance match drifts.
