TNC

TNC

The TNC series is a commonly used coax connector. Similar to the BNC, but with a screw coupling, this connector can be used up to 11 GHz. Both 50 Ω and 75 Ω impedances are available. Connector styles are available for flexible, conformable and semi-rigid cable types. Versions of the TNC connector are available for mounting to printed circuit boards using both through-hole soldered and through-hole press-fit techniques. Both crimp and clamp cable termination processes are used for this series. Applications for these connectors range from signal and data to video transmission where vibration resistance is required. TNC’s are a low-cost high-frequency solution for coax connections. Mating face sealing for TNC connectors between plug and jack (mated) according to IP 68. The classifications are general statements for the relevant series. Individual connectors may deviate from the values shown. If in doubt, please consult our engineers
