Coaxial connectors, or RF connectors, are typically used for the connection of a radio frequency transmission line such as an antenna or cable. The D4S20P-400A5-Z type of coaxial connector in particular is a PCB mount which is a popular choice for RF application designs.

It is especially suited to applications where robust and reliable capabilities are required. It has a strong environmental sealing ability due to its IP68 rating, meaning that it is dust tight and protected against long term immersion up to 1m in depth, enabling it to be used in a vast array of fields, such as automotive, medical, mobile device, and aerospace applications.

The 4 pole snap-in D4S20P-400A5-Z coaxial connector requires a flush mount on the PCB alongside a cable holder which is secured through the cable sheath. It has a central contact pin, a conductive thread nut, and a PVC housing which additionally feature a 360-turn release compared to the standard version.

The D4S20P-400A5-Z Coaxial Connector\'s features, including solder tabs on the inner contact as well as the contact pin connection, ensures a secure clamping of up to 3.5GHz. This helps to avoid detuning and losses of the transmission line so that it is able to work at high frequencies.

The central pin of this RF connector is available in different versions, including an extended pin which gives even more secure guidance during soldering with a higher melting point. This improved contact guidance also requires less soldering material to maintain its secure connection, thus aiding durability. Furthermore, the 4 pole snap-in connector has features like an easy-to-connect pin power module ensuring that it is easy to connect and has zero RF leakage.

In terms of RF properties, this type of coaxial connector shows low loss results in the frequency range of 1GHz-6GHz with a VSWR less than 1.4. This result is accomplished through the design of its contact-point which allows the length of the contact to be adjusted to fit the cable diameter, thus further emphasizing its reliability.

The wide range of features of the D4S20P-400A5-Z coaxial connector mean that it can be used for a variety of applications, notably those requiring robust and reliable connections. This makes it a useful choice for many high frequency electrical applications such as accurate broadband measurements and radio base stations.
