DCM-21WA4P-K87 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. Classification of D-SUB connectors

    ‌Solder cup D-Sub connector‌: This connector meets commercial industrial standards and can be paired with any docking solder cup D-Sub connector. The contacts are electroplated with flash gold, and the connector insulator meets the UL94V-0 standard. The maximum wire size is 20 AWG, and 9, 25, 37 and 50 pin specifications are available.

    ‌Crimp D-Sub connector‌: Crimp D-Sub connectors meet commercial industrial standards and can be used for most standard D-Sub male connectors. Compatible with 20-28 AWG wire range, available in 9, 15, 25 and 50 pin sizes.

    ‌Punch-type D-Sub connector‌: This connector is easily soldered into the through-hole of the printed circuit board or used in many other applications. Solder placement follows a standard footprint, and gold-plated contacts ensure long life. As an industrial standard commercial DB37 female PCB type connector, it has standard mounting holes for application flexibility.

  • 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. 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.
