Introduction

D-Sub Connectors or Data-Sub connectors are a type of electrical connectors commonly used in computers as well as utilities, communications, instrumentation, and automation devices. These connectors are typically deployed in applications, such as telecom, medical, industrial, automation, and aerospace & defense. The MDM-51PBRM7 is a D-Sub Connector produced by Mitsumi Electric Co. Ltd., a company established in 1932. The connector has nine pins, which makes it suitable for applications requiring multiple connection points, including motor control, for example.

Features

The MDM-51PBRM7 has several unique features that make it suitable for many diverse applications. Its pins are made from brass and have a gold-plating to make sure that signals are not disturbed and data is transmitted safely. The contact parts have axial and radial insulation materials to prevent short circuits. The outer case of the connector is constructed from PBT, which is a flame-retardant material that has been designed to resist high temperatures. The PBT case also ensures that external influences are kept away from the pins.

Application Fields

The MDM-51PBRM7 is suitable for a variety of applications, including motor control, telecommunications, medical equipment, consumer electronics, and industrial machinery. It is capable of transmitting and receiving analog and digital signals, making it suitable for tasks that require high-speed data transmission. Additionally, because of its PBT outer covering, the MDM-51PBRM7 can be used in harsh environments, including high- and low-temperature conditions, and high-electrical-noise environments.

Working Principle

The working principle of the MDM-51PBRM7 is relatively simple. The pins are electrically connected in series, meaning that the current is shared between the nine pins. When the connector is inserted into a device, the pins make contact with the corresponding pins on the device. The electrical current then flows from the device to the connector, allowing data to be transmitted and received. The insulation material, PBT outer covering, and gold-plating on the pins all work together to ensure that the data is transmitted with minimal disturbance.

Conclusion

The MDM-51PBRM7 is a D-Sub Connector produced by Mitsumi Electric Co. Ltd. It is suitable for many diverse applications, including motor control, telecommunications, medical equipment, consumer electronics, and industrial machinery. The connector has several unique features, such as flame-retardant PBT outer covering, nine pins that are gold-plated and insulated, and is capable of transmitting and receiving digital and analog signals. The working principle of the connector is relatively simple – when the connector is inserted into a device, the pins make contact with the device’s pins, and data is then transmitted and received safely.
