The 112586-13: It mates with any standard 75 Ohm BNC plug via a quarter-turn bayonet lock, giving a positive mechanical connection that holds under cable strain without threads. The through-hole solder termination anchors the centre conductor and shield to the PCB or panel, and the gold-plated beryllium copper centre contact keeps contact resistance low across 500 mating cycles.
Frequency and Signal Integrity
The PTFE dielectric maintains a stable 75 Ohm impedance across the band, and the nickel-plated brass body provides enough shielding for typical studio or head-end rack environments.
Mechanical and Environmental Ratings
The bayonet lock survives repeated connect-disconnect cycles in field-service scenarios — the 500-cycle rating is typical for a BNC interface that gets mated and unmated regularly, not a one-time install.
