Introduction to D-Sub Cables

D-Sub cables are a type of wiring used in various applications, such as medical, telecommunications, automotive, aerospace, industrial, and consumer electronics. These cables come in various sizes, configurations, and formats such as DB (Dual-In-Line), SFP (Small Form-Factor Plugable), LC (Locking Connector), and MDM (Miniature Data Mate). D-Sub cables are designed to allow system components to be connected with relative ease due to the connectors themselves providing a precisely machined mechanical connection along with a reliable electrical connection.

MDM-21SH041F-A174

The MDM-21SH041F-A174 is a type of D-Sub cable made up of a wire mesh shielding with gold-plated terminals and two plastic protective caps. It features a molded humanized body design for easy grasping and insertion, and has an integrated contact resistance of 20mΩ max. This cable is qualified for signal transmission between electronic systems in applications such as medical, aerospace, industrial, and telecommunications.

Application Field for the MDM-21SH041F-A174

The MDM-21SH041F-A174 is designed for a wide range of application fields. It is especially suitable for applications that require a high degree of interference-shielding in order to reduce the risk of signal errors or misinterpretations. Additionally, the small yet robust form factor makes this cable an ideal choice for applications where its compact size is highly beneficial. Highly rated for its mechanical and electrical reliability, the MDM-21SH041F-A174 can provide a reliable connection for various systems and components.

Working Principle of the MDM-21SH041F-A174

The working principle of the MDM-21SH041F-A174 relies upon the precise engineering of the individual components. The connection between two components is achieved through the use of a sealed contact system. This contact system is comprised of several parts such as a collar, a flange, and an O-ring which are designed to ensure a secure electrical connection. The contact surfaces between the male and female connector are also each treated with a gold plating which further enhances the electrical connection. This ensures that the connection will not fail under the conditions of high voltage or electrical interference.The signals passing through the cable are also protected from external interference by the use of a wire-mesh shielded cover. This shielding can effectively block out any electrical disturbances that may be present in the surrounding environment. Additionally, the cable has a dielectric strength of 500V and an additional shielding to further ensure that signals are accurately transmitted.

Conclusion

The MDM-21SH041F-A174 is a robust and reliable type of D-Sub cable designed for use in various applications, especially those which require high levels of interference-shielding in order to ensure accurate and consistent signal transmission. This cable has a molded humanized shape for easy insertion and grasping, as well as an integrated contact resistance of 20mΩ max. Its small, lightweight form factor makes it ideal for applications where space is of the essence. The precise engineering of the component parts and the use of gold-plated terminals and a wire-mesh shielded cover makes this cable highly resistant to electrical interference. This type of D-Sub cable is an excellent choice for any application where signal interference needs to be kept to a minimum.
