684M21W1103L461 Classification

D-Sub Connectors

D-Sub Connectors are widely used electronic connectors whose design is characterized by their unique D-shaped metal housing, a shape that not only provides mechanical support but also ensures the correct orientation and alignment of the connector, preventing misinsertion. The D-Sub connector consists of a series of parallel pins or hole pins that are embedded into a D-shaped housing that itself provides protection for the contacts, but also acts as a grounding path and as part of electromagnetic interference (EMI) and radio frequency (RF) shielding. The design principle of the D-Sub connector is based on the physical contact of the metal contact point, and the corresponding interface is connected through the spring-loaded metal contact to form a stable electrical connection. Its features include high reliability, ease of plugging, and a wide range of pin configuration options for varying density signal transmission needs.

FAQ about D-Sub Connectors

  • 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. Applications of D-SUB full range of connectors

    1. Computer field: D-SUB connectors are widely used in the computer field, such as the connection of external devices such as monitors, keyboards, mice, etc.
    2. Communication field: D-SUB connectors can be used for signal transmission between various communication devices, such as telephones, fax machines, routers, etc.
    3. Industrial control field: D-SUB connectors are widely used in the industrial control field, such as the connection of PLCs, sensors, actuators and other equipment.
    4. Automation field: D-SUB connectors can be used for signal transmission and power supply in automation equipment, such as robots, automated assembly lines, etc.
    5. Other fields: In addition to the above fields, D-SUB connectors can also be used in other fields such as security, lighting, and medical equipment.

  • 4. Problems caused by poor contact of D-SUB connectors

    Performance: increased contact resistance, circuit breakage, contact curtain movement, etc.

    Causes: inadequate connection, insufficient contact area, dirt, corrosion, oxidation, etc.
    Solution: Re-plug the connector, clean the connection part (use alcohol or other cleaning agents), replace the contact or connector.
