1. What is a D-SUB connector
The name of the D-SUB connector comes from the D-shaped appearance of its plug. It is a double-row cable connector widely used in computer, industrial automation and communication fields. This connector consists of two parts: a plug and a socket. It is connected through pinholes and pins. It can transmit video, audio and digital signals and provide a large number of grounding points.
The D-SUB connector is a compact and versatile connector mainly used to support power, analog, RF or digital signal transmission. It has a variety of models, options and accessories and is a very economical interconnection solution. -
2. Features of D-SUB connector
1. Easy plugging and unplugging: The D-SUB connector adopts a push-pull plug-in design, which is convenient and fast, and can quickly connect and disconnect the circuit.
2. Reliable contact: The contact of the D-SUB connector is made of high-quality metal material, which is precisely processed and gold-plated, and has good conductivity and long service life.
3. Wear resistance: The contact of D-SUB connector is made of wear-resistant material, which can withstand frequent plugging and unplugging and long-term use, and is not easy to be damaged.
4. Multiple specifications: D-SUB connectors have multiple specifications, suitable for different cables and sockets, and the appropriate specifications can be selected according to actual needs.
5. High reliability: The design of D-SUB connectors focuses on reliability. After strict quality control and testing, it can ensure that there will be no problems such as poor contact or short circuit during use. -
3. FAQ of D-SUB Connector
D-SUB connector connection is poor
