50 Ohm BNC Jack for 2 GHz Signal Paths
The Hirose BNC-R-PC-2(40) is a 50 Ohm BNC jack (female socket) with a bayonet lock, rated to 2 GHz. The 2 GHz ceiling is the 3 dB roll-off point; stay below it to keep insertion loss flat. The centre contact is beryllium copper with silver plating — beryllium copper gives the spring fingers their retention force after repeated mates, and silver keeps surface conductivity high at RF frequencies. The body is nickel-plated brass, the standard corrosion-resistant shell for indoor equipment.
5000 Mating Cycles — Built for Frequent Reconnect
This jack is rated for 5000 mating cycles — ten times the typical 500-cycle BNC. That matters when the connector lives on a test-equipment front panel, a patch panel, or any port that gets re-patched daily. The beryllium copper centre contact is what sustains that cycle life; the silver plating will wear over time, but the contact spring force stays within spec across the rated count. If you are specifying for a lab bench or a production test fixture, this is the BNC that outlasts the equipment.
Through-Hole Solder Termination — Field-Repairable
That means you can re-pin it on site with a basic soldering iron if the connector gets damaged or the cable needs replacement. No ground spring or ferrule to lose.
