D-Sub connectors are one of the most widely used connectors in applications ranging from automotive to instrument settings. The DCH-A-003 is a family of D-Shaped connectors with plastic threaded backshells, and other components such as flat-mount or round housings and plastic shield hoods.

This connector has a genderless configuration, which allows for simple mating of any two matching DCH-A-003s in any situation. The connectors conform to standard D-subminiature requirements with a 7.5mm pitch and a 9.48mm overall width. It is suitable for use with cables ranging from approximately 0.5-5.5mm in diameter.

Applications

The DCH-A-003 is ideal for applications such as computers, test and measurement equipment, telecommunications, signal processing, power control, audio, and video. With its 7 pin layouts, it is able to accommodate both the traditional Female-Female as well as the Male-Female contact arrangement. This range allows for multiple signal configurations, including communication and power circuits.

Working Principle

The DCH-A-003 features a threaded backshell, which provides EMI/RFI shielding. The backshell also provides a secure locking mechanism and ensures longevity and consistency of connectivity. The backshell is also resistant to vibration and provides strain relief for the cables and connectors in the assembly.

The hood covers the backshell, and the connector support provides safe housing of the connector. The cable can be attached with a solderless termination, which is highly reliable. Once the cable is connected to the connector the hood is then complete with a locking screw tight. The hood is also available in a variety of colors for added aesthetic value.

The materials used are highly durable and resistant to knocks and shocks as well as endurance against the changing climate and weather conditions. The metal contacts also provide a low contact resistance, ensuring a reliable and consistent connection.

The DCH-A-003 is a high-performance solution, suitable for a wide range of applications in the automotive, industrial, and consumer electronics. It is resistant to corrosion, temperature, vibration, and pressure, which enhances its suitability for a wide range of application environments.
