Barrel - Power Connectors

Category Introduction

Power barrel connectors are most commonly used to connect low-voltage DC power provided from a wall mounted AC-DC converter to small electronic equipment, such as laptop computers and printers. They are characterized by a tube-shaped plug having electrical contacts on the inner and outer surfaces. Various sizes are available, with inner diameter, outer diameter, and mating length of plug and jack needing to be compatible in order to achieve a proper connection.
