Application of 1655221

D-Sub Connectors play an important role in many fields such as computers and peripherals, communications and networking, industrial automation, and audio and video. These connectors are often used to realize the exchange of signals and data between devices, for example, in computer peripherals, they are used to connect computer peripherals such as keyboards, mice, printers, etc. In communication devices such as network switching devices, modems, routers, etc., D-Sub connectors are used to transmit data and signals. In industrial automation, they are used to connect PLCS (programmable logic controllers) and other control systems. In addition, the D-Sub connector is also an indispensable component in test and measurement equipment for data acquisition and transmission, as well as the interconnection of in-car networks in automotive electronics.

1655221 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. 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.

  • 3. FAQ of D-SUB Connector

    ‌What is the reason for no signal in D-SUB connector?
    Performance: No signal.

    Solution: Check whether the signal cable is plugged in properly and ensure stable connection. 3.

    ‌‌D-SUB connector causes the monitor to fail to display.
    Performance: The monitor cannot display.
    Solution: Adjust the computer resolution to the highest resolution supported by the monitor.

    ‌‌What is the reason for poor connection of D-SUB connector?
    Performance: Poor connection.

    Cause: The pin is exposed and easily damaged.
    Solution: Use a protective cover to avoid pin exposure and operate carefully.

  • 4. FAQ of D-SUB Connector

    ‌What is the reason for slow data transmission of D-SUB connector?
    Performance: Slow or interrupted data transmission.
    Cause: Inherent characteristics of serial communication.
    Solution: Use faster communication standards or increase communication stability measures ‌24.

    ‌‌D-SUB connector signal attenuation
    Symptom: Signal attenuation.
    Cause: Long-distance transmission characteristics.
    Solution: Use higher quality cables or add signal amplifiers.
