Product Description

This 75 ohm BNC crimp connector is a locking RF connector that is used on many types of coaxial cable. BNC connectors are commonly used on test equipment, avionics, analog and serial digital interfaces as well as video signals. BNC crimp connectors require a crimp tool for termination.

The BNC (Bayonet Neill–Concelman) connector is a miniature quick connect/disconnect radio frequency connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut. BNC connectors are used with miniature-to-subminiature coaxial cable in radio, television, and other radio-frequency electronic equipment, test instruments, and video signals. The BNC was commonly used with 10BASE2computer networks. BNC connectors are made to match the characteristic impedance of cable at either 50 ohms or 75 ohms. They are usually applied for frequencies below 4 GHz and voltages below 500 volts.

Similar connectors using the bayonet connection principle exist, and a threaded connector is also available. United States military standard MIL-PRF-39012 entitledConnectors, Coaxial, Radio Frequency, General Specification for (formerly MIL-C-39012) covers the general requirements and tests for radio frequency connectors used with flexible cables and certain other types of coaxial transmission lines in military, aerospace, and spaceflight applications.

FAQ

Q: What does BNC stand for?

A: BNC stands for Bayonet Neill-Concelman. They are named after the bayonet locking mechanism and their inventors.

Q: What are BNC connectors commonly used for?

A: BNC connections are typically used on RF, video and ethernet applications.

Q: How can I tell the difference between a 75 ohm and 50 ohm BNC connector?

A: On a 50 ohm connector the center pin is surrounded by a white dialectric. On a 75 ohm BNC connector is surrounded by air (no dialectric)

Q: Can a 50 ohm and 75 ohm BNC connector be connected together?

A: 50 ohm and 75 ohm BNC connectors will mate with each other. At frequencies under 10 MHz the impedance mismatch will not have any affect. If you are above 10 MHz the chances of signal distortion becomes more significant.
