50 Ohm BNC Plug for RG-55/223 Cable — What You Get in the Kit
The 5227079-6: The 500 V voltage rating and nickel-plated brass body with gold-plated centre contact give it the corrosion resistance and contact integrity for repeated field mating — 500 mating cycles are on the spec sheet.
This plug is crimped onto RG-55, RG-55B, and RG-223 coax — the shield terminates via crimp over the ferrule, the centre contact crimps onto the signal wire. The polyethylene dielectric keeps the 50 Ohm impedance stable through the assembly.
The 5227079-6 is listed as obsolete. There is no official replacement order code on record. Confirm the cable group and termination style match your harness before committing the line.
