MDM-25PL1B Application Field and Working Principle

Introduction

MDM-25PL1B is a special cable created by Amphenol, a company specializing in high-performance equipment and communication technologies. This cable belongs to the category of D-sub cables, which can be employed for other product lines, such as MIL-grade and consumer-grade products. It is made up of two components: the body and the connection modules. The body contains one or two separate modules, each of which contains a large number of pins arranged in specific patterns. The modules are connected to one another and to the main body by a series of insulated metal wires. This article will explore the application field and working principle of the MDM-25PL1B cable.

Application Field

The MDM-25PL1B cable is mostly employed in the defense and aerospace sectors, specifically, in applications where it is necessary to route signals and power supply between multiple units. This cable is also applicable to small, low-power consumer devices, such as laptops, single-board computers, and cell phones. Additionally, it can be used with test and measurement equipment, and in the industrial sectors, in machine- and process-control systems.

Working Principle

The MDM-25PL1B cable operates on the five-pin system, wherein two multibus connectors are connected by insulated wires with five different contact points: one for the power supply, three for the signal connection, and one for ground reference. The two multibus connectors are equipped with pins in specific patterns to ensure the proper connection between each pin in the cable. Each module has its own ground reference; however, both modules share the same common ground. When the modules are connected, current begins to flow from the power source to the pin contacts, creating a closed circuit. The power supply runs through the signal lines and the shared ground reference to the target device, and the signal lines provide the transfer of data. This process is repeated when the cable is unplugged and connected to other devices. The metal wires ensure that the connection is secure and can handle the current requirement from both the power source and the target device.

Conclusion

The MDM-25PL1B cable belongs to the category of D-sub cables, which are greatly used in the defense and aerospace sectors. This cable is capable of routing signals and power between different units, and it is suitable for small, low-power consumer devices. Furthermore, it can also be used with test and measurement equipment and in industrial sectors for machine- and process-control systems. The MDM-25PL1B cable operates on the five-pin system and is equipped with two multibus connectors connected by insulated wires with five contact points. These features guarantee the secure and stable connection between the power supply and the target device.
