Pisces Waterproof

"A Different Kind of Connector Manufacturer"


Typical Applications – Mil-Aero, Safety, Radar, Marine, SCADA and Telematics


This miniature sized connector series is similar to a BNC connector but with a threaded coupling mechanism rather than a bayonet fitting giving superior electrical performance at higher frequencies. This series is used with small and medium size cables. The TNC series also accommodates various PCB, flange and bulkhead configurations. They are generally used in applications up to 12 GHz. although ‘Precision’ TNCs are available up to 18 GHz.
