D-Sub Connectors

(Showing 24 of 28)

The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, ensures correct orientation, and may screen against electromagnetic interference.

Key Features and Benefits of D-Sub Connectors

  1. Durability and Reliability: D-sub connectors are designed to withstand harsh environments, making them ideal for industrial and heavy-duty applications. With robust metal housing and solid construction, these connectors ensure long-lasting performance even under constant use.
  2. EMI Shielding: Electromagnetic interference (EMI) can disrupt the performance of sensitive electronic systems. Many of the D-sub connectors offered by Evelta feature built-in EMI shielding, protecting signals from external noise and ensuring stable data transmission.
  3. Versatile Pin Configurations: D-sub connectors come in a wide range of pin configurations to meet the needs of different systems. At Evelta, we offer connectors with configurations like DB9, DB15, DB25, and DB37, in both male and female options. This flexibility allows them to be used in a broad spectrum of applications, from computer peripherals to communication systems.
  4. Through-Hole Termination: Many D-sub connectors in our selection come with through-hole termination, making them easy to install on printed circuit boards (PCBs). Through-hole connections provide excellent mechanical strength and are ideal for applications where durability is paramount.
  5. Compact Design: The "subminiature" in D-sub refers to the connectors’ compact size, making them ideal for devices with limited space. Despite their small form factor, D-sub connectors can accommodate multiple pins, ensuring a large amount of data or power can be transferred.

Applications of D-Sub Connectors

  1. Industrial Equipment: D-sub connectors are highly durable, making them ideal for use in industrial environments where heavy machinery requires reliable electrical connections. Whether it's for power transmission, control systems, or automation, D-sub connectors provide the necessary robustness for industrial use.
  2. Computers and Peripherals: D-sub connectors, particularly DB9 and DB25 configurations, are often used in older computer systems for serial communications, such as RS232 connections. Despite advancements in connector technology, D-sub connectors are still widely used for legacy equipment that requires these reliable serial connections.
  3. Telecommunications: Many communication systems rely on D-sub connectors to transmit data. Their ability to manage multiple signals and pins makes them a popular choice for audio-visual equipment, networking, and telecommunications systems.
  4. Consumer Electronics: In addition to industrial and communication applications, D-sub connectors are also found in consumer electronics, such as gaming consoles and audiovisual equipment. Their robust build ensures they can handle frequent plugging and unplugging without degradation.

How to Choose the Right D-Sub Connector

Choosing the right D-sub connector depends on a few key factors:

  1. Pin Count and Configuration: Depending on your application, you may need a specific pin count, such as DB9, DB15, DB25, or DB37. Consider the data transfer requirements and physical space available in your system to select the appropriate configuration.
  2. Male vs. Female: Male connectors feature pins, while female connectors feature sockets. Ensure you’re selecting the correct gender for your device or cable.
  3. Straight vs. Right-Angle: If space is a concern, a right-angle connector may offer more flexibility, especially in confined spaces where a straight connector may not fit.
  4. Mounting Type: If you are working with PCBs, ensure the connector has through-hole or surface-mount termination, depending on your installation needs.
