  • Which type of guide rail is used for distribution boxes

    Which type of guide rail is used for distribution boxes

    DIN rail is a standardized metal rail used for mounting industrial control equipment inside equipment racks and enclosures. Defined by standards such as IEC 60715 and EN 50022, the most common type is the 35mm “Top Hat” rail (TS35). What are DIN Rails? DIN is the short form for Deutsches Institut für. Guide rails, also known as linear guides, are mechanical elements designed to ensure smooth, precise and controlled linear movement of objects. They generally consist of two main components: the rail itself and a sliding carriage that moves along the rail. The carriage is often fitted with bearings. That's the magic of DIN rails —those slim metal strips that hold everything together. Steel guide rails are used in a variety of applications, including conveyor systems.
