Connectors
Electrical connectors are devices used to join electrical terminations and complete a working circuit. Connectors work in pairs: plugs (male) and jacks (female). Hundreds of connector types exist for power, signal and control applications.

A wide variety of characteristics help determine the use case for a connector. Different connectors have different pinouts, contact resistance, insulation, sizes, ruggedness, resistance to external hazards, and more. Different physical construction styles exist to easily differentiate one type of connector from another. Connector pairs share most if not all characteristics, and can’t work with a plug or jack of another type.

Common connectors include cam-style, circular, coaxial, pin and sleeve, rectangular, straight blade, and mechanical for splice and reducing. Many include twist locks and are keyed to prevent disconnection and ensure the correct plug joins with the correct receptacle.
