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. -
