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. Specifications and models of D-SUB connectors
There are many specifications and models of D-SUB connectors, and the common ones are D-SUB 9-pin, D-SUB 15-pin, D-SUB 25-pin and other series. These series have their own scope of application and characteristics. Users can choose the appropriate specifications and models according to actual needs. At the same time, the prices of different specifications and models are also different. Users need to consider factors such as cost and applicability when choosing.
