This twist-on 50 ohm BNC 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. Twist-on connectors do not require any crimping tools making terminations easy.

A: BNC connectors are miniature quick connect/disconnect radio frequency (RF) connectors used for coaxial cable that work with video and ethernet applications.
Q. What do I need for proper installation?
A. A coax stripper, coax cable, and the BNC connector are all needed for proper installation.
Q: What does it mean when a connector says it is 50 ohm or 75 ohm?
A: BNC connectors are most commonly made in 50 and 75 ohm versions. Video and DS3 Telco central office applications primarily use 75 ohm connectors, while 50 ohm connectors are used for data.
You can easily tell the difference between the two by looking for the dialectric. The 50 ohm connector features a white dialectric surrounding the center pin, while the 75 ohm BNC connector is surrounded by air (no dialectric).
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 become more significant.
Q. What is the benefit of this twist on connector over other styles?
A. Twist on connectors are one piece connectors do not require any termination tools other than the strip tool. They are great for a quick installation.
