Coaxial Connectors (RF): 142-9403-011 application field and working principle

Introduction

Coaxial connectors (RF) are specialized types of connectors designed for use in electronic circuits carrying radio frequency (RF) signals. The application of a particular type of coaxial connector depends on the type of signal frequencies that need to be transmitted, and the type of equipment being used. A 142-9403-011 connector is a specific type of RF coaxial connector, and has particular applications and operating principles.

Application Field

The 142-9403-011 connector was developed by Amphenol Corporation for mission-critical usage in military and commercial aerospace systems. Being highly reliable and environmentally resilient, the 142-9403-011 is very suitable for harsh conditions of outdoor and indoor applications. Being one of the smallest RF connectors, it can be used for a broad range of different devices, from aerospace to telecommunications. The 142-9403-011 also features a waterproof seal, making it very suitable for applications like military communications systems, GPS tracking, radios, and outdoor activities like camping and hiking. It is particularly suitable for small, portable electronic devices where space is an issue. The 142-9403-011 can also be used in industrial and medical applications, where its waterproofing capabilities come in handy.

Working Principle

The 142-9403-011 operates by electrical conduction and signal transmission. This process takes place internally, and is not visible externally. The tensile strength of the 142-9403-011 ensures that it is highly resistant to normal wear and tear. It also boasts excellent electrical conductivity thanks to its superior plating and contact design. The signal transmission of the 142-9403-011 occurs through the transfer of RF signals from one side to the other via the internal electrodes present in the connector\'s design. This happens when the connector is inserted into a socket or port, ensuring a reliable connection between the two devices. The insertion process also creates a watertight seal, which ensures that no water enters the interior of the device and damages its internal components.

Conclusion

The 142-9403-011 is a robust, highly reliable, and waterproof RF coaxial connector, designed for military and aerospace applications. Its small size, high tensile strength, and excellent electrical conductivity make it well-suited for a variety of applications. Its reliable signal transmission and watertight seals enable it to be used in conditions where robustness and reliability are a must.
