What is a connector?

Connectors components help join electrical circuits together. A connector can either join two wires together or connect one wire to a terminal. Connectors usually are designed with a “keyed” method to avoid having the parts mate with incorrect parts. Did you know there are over hundreds of different types of connectors in the electronic component family? To name a few: backplane, banana, barrel, blade type power, modular, rectangular, terminal blocks, and many more.
