D-Sub Cables have been around for many years, and have been used in a wide variety of applications and industries. The most common use is for computer connection, but they can also be used for industrial, networking and audio/video connections. One of the most popular D-Sub Cables is the MDM-9PHC20K. This article will discuss the application field of the MDM-9PHC20K and its working principle.

Application Fields

MDM-9PHC20K is a D-Sub Connector with high frequency digital EMI/RFI protection. It is designed to provide an effective solution to electromagnetic interference (EMI) and radio-frequency interference (RFI) by shielding the internal components of the connector from external sources of interference. It is suitable for low to medium power applications such as military, aerospace, computers, instrumentation, communications, medical devices and other electronic and electromechanical applications. The connector is also immune to shock and vibration, making it ideal for the harsh environment of military and aerospace applications.

Working Principle

The MDM-9PHC20K has a unique construction that allows it to effectively protect the internal components of the connector from external sources of EMI. The connector consists of two sections—a base section and a cover section. The base section connects the shielded cable and the cover section provides the shielding. The two sections form a shielded chamber that is sealed by ultra-wide range frequency gaskets which transmit signals through the shielding channel without the risk of EMI/RFI interference. The shield also reduces mechanical noise and crosstalk from nearby cabling.

The connector also has a built-in grounding system that prevents static charge accumulation and dissipates any EMI/RFI signals it encounters. The grounding system consists of two contact pins that are connected to the clean shell of the connector. The pins are connected to a ground plane and the plane is connected to the ground terminal of the power source. This ensures that the connector is grounded and protected from any potential EMI/RFI interference.

The MDM-9PHC20K is UL, CSA, VDE, and CE certified and can be used in a wide range of applications including aviation, defence, medical, industrial, automotive, computing, communications, and instrumentation. The connectors have a rated voltage of 400V and a rated current of 1A, making them suitable for medium power applications. The connectors are available in different sizes and various shell materials, making them compatible with most application areas.

Conclusion

The MDM-9PHC20K is a versatile and reliable D-Sub Connector with high frequency digital EMI/RFI protection. It is suitable for medium power applications and its unique construction provides effective protection against EMI/RFI interference. The connector is UL, CSA, VDE, and CE certified and is available in various sizes and shell materials, making it an ideal solution for a wide range of applications.
