D-Sub Cables

MDM-25SH023K Application Field and Working Principle

D-Sub Cables are widely used in both commercial and industrial connections, as they are capable of carrying a wide range of signals, from low-speed digital to high-speed video signals. The MDM-25SH023K is one of the most popular D-Sub Cables, due to its flexible and reliable connection option.MDM-25SH023K is a compact mini D-Sub cable featuring 25-pin connectors and a metal hood for protection against mechanical stress. It is typically used for RS232 applications, as well as RS232/422/485 applications. The MDM-25SH023K is capable of data transmission speeds of up to 115 kbps and is suitable for connecting various industrial, scientific, and avionic devices. The cable is made of 26-gauge copper wire and uses a thermoplastic elastomer (TPE) insulation for improved tensile strength. The connector body is made with machined-metal and the pins and contacts are gold-plated for reliable contact and better shielding. The cable also features an additional shielded layer for improved electromagnetic compatibility.The MDM-25SH023K application field and working principle are quite simple. The connector is designed to be compatible with standard DB25 style connections, and can be connected to either an RS232 or RS422/485 device. The pins on the cable connector are connected in pairs with two signal pins and one ground pin. The cable is then connected to the appropriate device and data is transmitted through the pins. The two signal pins on the connector are used to transmit data from one device to another via the RS232 protocol. The ground pin creates an electrical connection to the ground and is used to reduce ground-currents and un-necessary signal interference. The shielded layer protects the signal from electromagnetic noise by providing a barrier between the source and the device, thereby reducing errors in transmission.Overall, the MDM-25SH023K is an excellent cable for connecting various devices, such as scanners, printers, computers, test equipment, and more, for data communication and control. It is flexible and reliable, and is highly recommended for connecting industrial, scientific, and avionic equipment.
