A DIN rail is a component rail-mounting system for equipment cabinet racks. ’DIN’ refers to ’Deutsche Institut für Normung’, which is a global industry standard. They are made up of a long metal strip to which electrical and industrial control products can be attached, such as terminal blocks, circuit breakers, power supplies, and more. They are a convenient mounting method as components can be snapped or slid into place, and they are also space-saving.
