Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices

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

Audio connectors are used to affix cables to other audio equipment, providing electronic signal transference and grounding protection

Instrument and computer (disk drive) power connectors are available in two basic styles. The larger size, often called a Molex connector, is keyed and used on most internal drives. The smaller size, a mini-plug, is used for newer style disk drives

Patch panels are groups of ports used to connect lines between communications and electronic devices. Connections are made manually with small patch cords, and are easier to wire than automatic switches. Wireless patch panels are also available

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.

Serial communication adapters provide one or more serial ports to a host computer. They interface with the host computer via a data bus and add RS232, RS422, RS485 and/or other types of serial ports.

Fiber optic connectors are used to align and join two or more fibers together to provide a means for attaching to, or decoupling from, a transmitter, receiver, or other fiber optic device

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

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

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. 

RF and microwave connectors are used to connect the ends of cables in systems that operate in the radio frequency (RF) or microwave spectrum. They include threaded or bayonet-style couplings that snap, screw, or push into place

Micro connectors and nano connectors exhibit contact pitches of 0.05'' (micro) and 0.025'' (nano), respectively

DIN connectors are high frequency, multi-pin, electrical connectors that meet standards established by Deutsches Institut für Normung (DIN), a German national organization for standardization. The ends of DIN connectors are round, notched, and protected by a metal skirt to ensure that pins line up correctly

Circular connectors are multi-pin connectors primarily used for external interfacing
