Coaxial connectors (RF) have a long history, but the concept of 122490RP application field and working principle are relatively recent developments for RF engineers. This article aims to analyze the principles of the 122490RP connector and its application range.

Overview

The 122490RP connector, also known as the Low Profile Coaxial Connector, is a coaxial RF connector manufactured by 3M which is compatible with semi-rigid and flexible cable types. It is designed to offer low insertion loss performance and minimal dielectric losses, making it an ideal solution for a wide range of applications. The 122490RP is designed for reliability and durability. It is rated for up to 1000 mating cycles, with a maximum insertion loss of 0.2dB. It is designed to operate in environments with temperatures ranging from -55°C to +155°C, and is rated for up to 500 flexing cycles.

Working Principle

The 122490RP connector consists of two identical stainless steel parts, one end being a female contact and the other end being a male contact. A contact spring is located inside the connector which exerts contact force on the contact pins. This spring is held in place by the housing and is compressed by the mating of the contacts. The electrical connection is established by the contact pins, which are notched to ensure proper polarization. In addition, the 122490RP connector has an internal grounding system which helps eliminate noise and protect the contacts from EMI interference.

Applications

The 122490RP connector can be used in a variety of applications. It is commonly used in telecommunications, wireless networks, medical imaging, aerospace, and other high-frequency applications. It is also used in military/aerospace applications where signal integrity and safety are of high importance. The 122490RP can also be used in Interface Fatigue Test (IFT) applications, which is a test to measure the fatigue resistance of electrical components.

Conclusion

The 122490RP connector is a reliable and rugged RF connector, designed for use in a wide range of applications. It is designed to offer low insertion loss performance and minimal dielectric loss, as well as a high mating cycle rating and extended temperature range. The 122490RP can be used in an array of applications, ranging from telecommunications to military/aerospace applications, and is an ideal choice for reliable and durable RF connections.
