BNC and TNC Connectors
San-tron's extensive lines of BNC and TNC connectors and adapters are available as male and female cable
connectors for cables with diameters from 0.150 to 0.250 inches (versions are also available for cables with
diameters from 0.094 to 0.420 inches), and as receptacles with panel, bulkhead, press-fit, and threaded mountings.
BNC connectors join with a quick-disconnect bayonet-locking coupling mechanism, while TNC connectors employ a
screw-type, threaded connection for harsh environments. The connectors and adapters are constructed of brass
with heat-treated, beryllium-copper, female center contacts, with a variety of finish options including silver,
nickel, albaloy, or gold plating in any combination. All San-tron BNC connectors mate with connectors and adapters that incorporate
MIL-STD-348 BNC interfaces, while all TNC connectors mate with connectors and adapters based on
MIL-STD-348 TNC interfaces.
