BNC CONNECTOR SERIES

The BNC is a bayonet style connector allowing for quick connect and disconnect with a positive locking mechanism. Mating is achieved with just a quarter turn of the coupling nut. With a classic, dependable design, BNCs are suited to accommodate a large variety of RG and industry standard cables, in a variety of termination styles.

Amphenol offers a full line of BNCs in a multitude of options. From 50 Ω to 75 Ω Impedance, Commercial to Military grade, BNC connectors are miniature, lightweight and reliable. A full line of printed circuit board receptacles, bulkhead receptacles, reverse-polarity connectors, resistor terminations, and other accessories complement the product offering.
