Introduction to Coaxial Connectors (RF) - Adapters

Coaxial connectors are a type of RF (radio frequency) connectors that are used in radio and television apps. They are primarily used to join two signals in the same transmission line. These RF connectors are also known as coaxial cables or coaxial adapters. An adapter is a device that enables communication between two different components and is usually attached to the end of a coaxial cable.

142-1901-821 Application Field and Working Principle

142-1901-821 is a type of SMA (Sub Miniature A) coaxial connector which is created to provide a reliable electrical connection in various applications. It is widely used in radio, TV and satellite broadcasting systems, as well as in wireless communication systems. The connectors are available in both male and female versions and come with a 3.0 mm diameter center contact pin.

These connectors are constructed of high-quality materials, such as brass, stainless steel, and nickel plating for superior corrosion resistance and strength. The outer contact is designed to provide a secure connection with the device and to resist heat. It is also designed to be waterproof and to prevent shorting out of the circuits.

The working principle of 142-1901-821 is based on the RF connection between two devices. The connectors use a threaded contact point that is tightened by turning the outer part of the connector. This creates a secure and strong connection between the two devices. The connection is also able to transfer signals, data and power at higher frequencies. The connectors also do not require an external power source, as they are powered by the RF signal itself.

These coaxial connectors also have several applications, such as in college campuses, corporate buildings, hotels, businesses, data centers, and residential areas. They are also used in high-performance audio and video systems, and in satellite communications. Additionally, they are used in radios, cellular networks, cellular phones, and other wireless communication devices.

Conclusion

142-1901-821 is a type of coaxial connector that can be used in a variety of applications. They are reliable and provide a secure connection between two components. Furthermore, they also offer high frequency signals, data and power transmission. In addition to its wide application field, these connectors are also waterproof and corrosion-resistant.
