Coaxial Connectors (RF) are one of the most widely used types of connectors found in the telecommunications industry. They\'re highly versatile and cost-effective due to their versatility, low signal loss, and wide variety of applications. The D4S20P-400A5-D is one of the most popular coaxial connectors from Amphenol RF, and is designed for general use in the telecommunication, industrial, medical, consumer, automotive, and other markets. This connector uses a push-on connection system which provides quick and reliable connections.

The D4S20P-400A5-D is a four-conductor, 20-contact interface with a push-on connection system. It uses a direct-contact electrical contact interface and is rated for up to 10A. It has a frequency range of 0-400 MHz and an impedance of 50 ohms. It has a high insulation resistance of more than 1000MΩ and a low VSWR of 1.3:1. It is designed for easy and reliable termination and is compatible with a variety of mating connectors and cable types.

The D4S20P-400A5-D is typically used in applications such as base stations in cellular telecom and mobile radio systems, test instruments for medical equipment, navigation and avionics systems, and analog communications systems. This coaxial connector is also used in applications such as data terminals, cable TV systems, navigation systems, and other low voltage applications.

The working principle of the D4S20P-400A5-D is based on the principles of direct-contact electrical interface and impedance matching. This ensures that signals are transmitted accurately and without distortion. The center conductor of the connector carries the signal, while the outer conductor (shield) prevents electromagnetic interference from entering the cable. The impedance of the center conductor is matched to the impedance of the outer conductor by the dielectric filled between the center and outer conductor, thus ensuring an exact match between the signal and the impedance of the environment in which it is transmitted.

The D4S20P-400A5-D has a low-profile design that allows for space savings and ease of use. It is also RoHS compliant and has a wide operating temperature range of -65 to +85°C (-85 to +185°F). This makes it an ideal choice for applications that require a secure, reliable connection in harsh environments. Overall, this connector is an excellent choice for a variety of applications that require a robust connection with minimal signal loss.
