D-Sub Connectors

D-Sub Connectors, also referred to as D-subs, are a miniature type of connector developed by IBM and widely used in low-voltage applications. Derived from the word “duplex”, meaning its ability to have both input and output, the connectors span from 9 pins to 60 pins and can also be joined together to form compound connectors.

One model of the popular D-sub connectors is the MDM-9SL83B. This 9-pin model is commonly used in both commercial and industrial applications for data transmission. Its small size makes it ideal for use in applications with limited space or weight.

Application Field of the MDM-9SL83B

The MDM-9SL83B is most commonly used in low-power data transmission. It is particularly suited for connections between computer peripherals and other digital or analog devices. This includes connections between cellular phones, audio and video players, industrial devices, PLCs (Programmable Logic Controllers) and microcontrollers.

The connector can also be used in other digital and analog applications, such as audio, video, Ethernet, serial and parallel communication in both commercial and industrial environments.

Working Principle of the MDM-9SL83B

The MDM-9SL83B is designed for two-way communication. It is a 9-pin connector with a standard D-shaped backshell. This allows it to be used for both serial (3-wire) and parallel (4-wire) communication.

For serial communication, the connector transmits data over two lines: one for communication and one for clock signal. The third pin is used to ground the device.

For parallel communication, the connector supports four lines: two transmit lines, a receive line, and a ground line. This allows data to be transferred at a higher rate.

The MDM-9SL83B is designed to operate on a nominal voltage of 12V with a current rating of 0.5A. Maximum voltage of up to 16V and current of up to 1A can be achieved with this model.

The MDM-9SL83B connector features two screw locking mechanisms to ensure a reliable connection between the two devices. The connector is also designed with a series of anti-vibration and EMI protection features that help reduce external interference and ensure stable data transmission.

The MDM-9SL83B is an ideal choice for low-power data transmission applications. Its small size, robust construction and EMI/RFI protection make it an ideal choice for both commercial and industrial applications.
