About D-subminiature Connectors

D-subminiature or D-sub connectors are sturdy electrical connectors with a mating face shaped like the letter D. They provide polarization because male and female connectors can fit together in only one way. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets for pins from other devices. The number of pins or sockets in D-subminiature connectors corresponds to the number of wires in the cable. To accommodate different arrangements of pins, D-subminiature connectors are available in five standard shell sizes: DA, DB, DC, DD, and DE. The contact pitch or distance between pins ranges from as small as 0.0197'' or 0.5 mm to as large as 0.20” or 5.08 mm. High-density and double-density pin arrangements are commonly available. Combination connectors reduce the number of regular pins to accommodate larger coaxial, high current, or high voltage contacts.

Products & Services Related to D-subminiature Connectors

Coaxial Connectors

Coaxial connectors are composed of an insulated central conducting wire wrapped in another cylindrical conductor (the shield). The cable is usually wrapped in another insulating layer and an outer protective layer. Coaxial cables and connectors have the capacity to carry vast quantities of information. They are typically used in high-speed data and CATV applications.

Edge Card Connectors

Edge card connectors are edge-on connectors designed for single-sided or double-sided printed circuit boards (PCBs).

Gender Changers

Gender changers are devices that change the end of a cable into another type, allowing two cable assemblies with the same or different genders to mate.

Heavy Duty Rectangular Connectors

Heavy duty rectangular connectors are designed to accommodate large electrical loads and direct signals under a multitude of operating conditions.

Military (MIL-SPEC) Connectors

Military (MIL-SPEC) connectors are built in accordance with military specifications. Their design takes into account the need to protect the connection from environmental factors, allowing them to be used in military and aerospace applications.

Modular Connectors and RJ Connectors

Modular connectors and RJ connectors are plug-in units used in many networking and telecommunications applications. Registered jack (RJ) connectors are a type of modular connector, which often have protective capabilities such as integrated filters to protect against unwanted signals or some type of magnetics to provide filtering, signal conditioning, and isolation.

USB Connectors

USB connectors are used with universal serial bus (USB) ports. They can be used to connect USB products together, or to connect USB wires and peripherals to other standard port types.
