The dielectric is polyoxymethylene (POM) acetal. This plug terminates RG-59, RG-59B, RG-62, RG-140, RG-210, and Belden 8241, 8263, 8279, 9209 cables. The bayonet lock provides quick connect/disconnect with positive retention. Rated for 4 GHz maximum frequency at 50 Ohm impedance with 0.2 dB insertion loss. The 500 mating cycles suit field-service and test-equipment applications where repeated connect/disconnect is expected. The voltage rating is 500 V.","metaTitle":"31-321-RFX BNC Plug, 50 Ohm, 4 GHz, 500 Cycles","metaDescription":"Amphenol RF 31-321-RFX BNC plug, male pin, 50 Ohm, 4 GHz max, 0.2 dB insertion loss, 500 mating cycles.
