An Introduction to Sub Connectors

Sub connectors are a type of electronic connectors that have a D-shaped metal shell and multiple pins for signal or power transmission. They are also known as D-sub connectors, D-subminiature connectors, or DB connectors. They are widely used in various applications, such as data/computing, telecommunications/networking, industrial automation, defense, aerospace, medical equipment, and more.

There are different types of sub connectors, such as standard, high-density, mixed-layout, waterproof, etc. They also have different materials, such as steel, brass, stainless steel, aluminum, plastic, composite, etc. Each type and material has its own advantages and disadvantages, depending on the specific requirements of the application.

Some of the features and benefits of sub connectors are:

Performance: They can withstand high temperature, high vibration, shock, corrosion, and other environmental factors that may affect the electrical connection.
Flexibility: They offer a wide range of contact sizes, wire gauges, current ratings, coupling mechanisms, and shell options to suit different needs and preferences.
Reliability: They are built to meet international standards and specifications for electrical performance and quality. Some of them are qualified to the MIL-DTL-24308 specification for military use.
Protection: They can provide protection against EMI/RFI interference, fire hazards, gas leakage, water ingress, and other potential risks.
