Introduction to Coaxial Connectors

Coaxial connectors are used in almost any radio frequency (RF) applications, including cable television (CATV), satellite television, home theater systems, data communication systems, cellular and other mobile communication systems, and wireless communication systems. The most basic type of coaxial connector is the PL75-7, a 50 Ohm connector that is often used to connect coaxial cables to antennas, amplifiers or other devices.

PL75-7 Connectors

The PL75-7 coaxial connector has been around for more than 40 years and is still one of the most popular connectors for use in many RF applications. It has a threaded barrel for connecting to a coaxial cable or antenna, and a snap-on sleeve for connecting to a device. The threaded barrel is made of brass and the snap-on sleeve is made of polycarbonate. The male PL75-7 connector has a 1/4-inch diameter, and the female connector has a 3/8-inch diameter.

Applications of PL75-7 Connectors

PL75-7 connectors are used in a variety of applications, including television antennas, wireless connections, antennas for ham radios, radio frequency (RF) amplifiers, antennas for radio receivers, Marine VHF radios, and GPS antennas. These connectors are also used in satellite television systems, digital audio, and remote control applications.

Working Principle of PL75-7 Connectors

The PL75-7 connector works by using a threaded barrel to connect the coaxial cable to the device it is connecting to. The threaded barrel has internal threads that the cable is inserted into, and the cable is held in place with a snap-on sleeve. The threaded barrel is designed to be twisted to make a secure connection between the cable and the device the cable is connected to. The snap-on sleeve helps to provide a good electrical connection between the cable and the device, while also providing strain relief to protect the connector from damage.

Conclusion

PL75-7 connectors are popular for use in a variety of radio frequency applications, including television antennas, wireless connections, antennas for ham radios, RF amplifiers, and GPS antennas. They are designed to provide a secure connection between a coaxial cable and a device, and they have a threaded barrel for easy installation. The snap-on sleeve provides strain relief and a good electrical connection so that the connector will last.
