If your cable is in that group, the ferrule ID and center contact pin diameter are a match. The sibling 31-315-RFX targets RG-174/316 class cables instead, so pick the one that fits your coax diameter. ## Termination: Crimp or Solder The center contact accepts either crimp or solder termination — your choice depending on tooling and production volume. The shield is crimped using the included ferrule, a standard BNC field-install method.","metaTitle":"31-320-RFX BNC Plug, 50 Ohm, RG-58, 4 GHz, Crimp Termination","metaDescription":"31-320-RFX BNC plug, male pin, 50 Ohm, 4 GHz, crimp/solder termination, RG-58 cable group, 500 mating cycles.
