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

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

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

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. 

Computer board and card edge connectors are used inside personal computers to connect disk drives, CD drives, and serial and parallel ports to the motherboard

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

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

AC power connectors transfer alternating current through a variety of electronic devices. AC power connectors include simple AC inlets, outlets, and power entry modules

PCB pins and PCB receptacles are electronic interconnect devices for printed circuit boards (PCB). PCB pins are male connectors. PCB receptacles are female connectors

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

Power connectors transfer AC or DC through a variety of electronic devices and are used in a variety of commercial, industrial, and residential applications. Power connectors range from simple AC or DC inlets and outlets to sophisticated power entry modules

Centronics connectors are standard parallel interface devices for connecting printers and other peripherals such as portable disc drives, tape backup drives, and CD-ROM players to computers

PCB terminal blocks are modular, insulated devices that mount on printed circuit boards (PCBs) and secure two or more wires together. Some have integral pin terminals and mount through holes in the board. Others plug into PCB-mounted pin strips
