Application of L77TWB9W4PP3SYRM53

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.

L77TWB9W4PP3SYRM53 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. 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.
