The 0.2 dB insertion loss figure confirms the impedance match is held tight through the connector body, so the signal sees a continuous 75 Ohm path from cable to cable.","metaTitle":"Amphenol RF 112556B BNC Plug, 75 Ohm, 500 Cycles","metaDescription":"Amphenol RF 112556B BNC plug, male pin, 75 Ohm impedance, 0.2 dB insertion loss, 500 mating cycles, bayonet lock.
