Introduction

D-Sub Cables, also called DB cables, are commonly used to connect electronic or computer equipment within a system. The MDM-21SH004M2-F222 cable, in particular, is an RS-422 serial port communication cable with a two-section configuration, consisting of two shielded sections, a twisted pair wire, and two 24-pin connectors.

Application Field

The MDM-21SH004M2-F222 cable is suitable for a wide range of industrial applications, from machine tool monitoring and control to measuring and regulating systems. It is also useful for connecting multiple serial ports, allowing data transfer between two PC communication devices, or collecting data from remote locations.The two sections of this cable are designed to provide excellent protection from electromagnetic interference, making it an ideal choice for conveying noisy signals. It can also be used in a wide range of temperatures, from -40°C to 105°C, making it suitable for use in harsh environments.

Features and Benefits

The MDM-21SH004M2-F222 cable has several features that make it an attractive option for industrial applications. First, it has a high-flexibility outer jacket and can be bent into a variety of shapes, making it convenient to use in tight spaces. Second, it has an operating frequency range of up to 1500 MHz, and a large impedance range (100-1000Ω), allowing data transmission across long distances. Third, it is RoHS and UL compliant, providing assurance of safe and reliable connections. Fourth, it has a gold-plated surface, with superior signal transmission capabilities. Finally, it has an IP67 rating, meaning that it is dust tight and waterproof.

Working Principle

The MDM-21SH004M2-F222 cable uses RS-422 protocol for communication. This protocol works by converting serial bit streams (asynchronous data) into parallel bit streams (synchronous data). The two sections of the cable, consisting of shielded pairs of wire, are used to send and receive signals from the devices.The pins in the connectors contain two types of signals: the transmission (TXD) and the receive (RXD). The TXD signals are sent from the transmitting device, while the RXD signals are received from the receiving device. In addition, there are pins for ground and power, which provide the necessary voltage to the devices that are connected to the cable, allowing them to function correctly.

Conclusion

The MDM-21SH004M2-F222 represents a reliable and reliable choice for a wide range of industrial applications. Its features and benefits make it ideal for environments where toughness, reliability, and signal transmission are important. This cable is built for maximum performance and can withstand harsh conditions while ensuring superior signal transmission and rapid response.
