BNC Connectors

BNC ConnectorBNC connector has middle size in various RF connectors. BNC Connector is designed to have two-stud bayonet locking and BNC connector series are available for RF cables type, PCB type and adaptors. BNC Connector commonly is used for 0~4GHz (50 ohm) and 0~1GHz (75 ohm) , but offers 11 GHz max.

Wellshow Technology manufactures various BNC connectors and custom BNC RF cable assemblies in Taiwan. We can provide good quality in short time and welcome OEM or customized RF connector. Contact us by email or call us 886-2-24270488 to start business!

Information


The BNC coaxial connector was developed with a two-stud bayonet mechanism for rapid and reliable connection and disconnection.

BNC low-cost connectors typically utilize die-cast and molded components, while performance will not be equal to the industrial or military grade products, BNC connectors are used in broadcast, CATV and CCTV applications crimped with 75 ohm coaxial cables like RG179, BT3002, 2.5C2V, RG59 and RG6U.

BNC connector have 50 and 75 ohm impedance and offer broadband capability from 0 to 4 GHz. The 75 ohm BNC can be used successfully up to 1 GHz.
