The bayonet lock gives a quick quarter-turn mate — standard for BNC interfaces in broadcast video, test instrumentation, and low-power RF distribution where the 75 Ohm impedance matches the cable and equipment. The centre contact is brass with gold plating; the zinc body gets a nickel finish. It is a single-port, free-hanging (in-line) connector terminated by crimp on both the centre contact and the shield. ## Cable match and termination This plug accepts RG-179, 179A, 179B, 187, and 187A cable — the 75 Ohm flexible coax family common in CCTV, SDI video, and serial data links. The crimp termination covers both the centre conductor and the braid shield; the dielectric is polyethylene. For a harness builder, crimp tooling for the 0.100-inch centre pin and the ferrule is standard across the BNC crimp die sets. The 500 mating cycles rating means it holds up in test-rack or patch-panel duty where connectors are re-mated regularly. ## Lifecycle and sourcing — obsolete, sourced per RFQ The 221185-8 is listed as Obsolete by TE Connectivity. No official successor order code is recorded in the lifecycle entry. If your design can accept a parametric alternative, the 75 Ohm BNC plug family from TE (base number 221185) has multiple active variants; cross-referencing the cable group and plating grade against an active order code is the next step.","metaTitle":"TE Connectivity 221185-8 BNC Plug, 75 Ohm, 2 GHz, Obsolete","metaDescription":"TE Connectivity 221185-8 BNC plug, male pin, 75 Ohm, 2 GHz, 500 V.
