Product details

75 Ohm Mini BNC for Video and Telecom Signal Paths

The 031-70249: The mini BNC form factor (Connector Style: BNC, Mini) reduces panel cutout size compared to a standard BNC.

What 500 Mating Cycles Means for Field Life

If you are wiring a piece of equipment that gets plugged and unplugged a few times a week, 500 cycles gives you years of service before the contact starts to fret.

Through-hole mounting (Mounting Type: Through Hole) with a solder cup for the center contact and a solder tab for the shield (Contact Termination: Solder, Shield Termination: Solder). The body is nickel-plated brass (Body Finish: Nickel, Body Material: Brass), the dielectric is PTFE (Dielectric Material: Polytetrafluoroethylene (PTFE)) — the same material used in low-loss coax, so the signal path stays clean up to the connector's rated frequency. The bayonet lock (Fastening Type: Bayonet Lock) gives a positive, tool-less mate that resists vibration loosening better than a threaded coupling in a panel-mount scenario.
