Din Rail

Din rails are industry-standard metal rails that are used for mounting components inside of electrical control panels and cabinets. They are designed for securely attaching terminal blocks, circuit breakers, actuators, power supplies, solenoids and so on. Din rails are part of a universally interchangeable rack-mounting system that is used across countless industries around the world. The standardized widths and shapes of Din rails makes it possible for uniformity across all relevant products regardless of the manufacturer.

Din rails are made of various base metals, such as stainless-steel, aluminum, steel and copper. They have various finishes with respect to the base metal. The most common combination is zinc plated, yellow chromated steel. When selecting a Din rail, it is important to consider the environment, the enclosure material, the short circuit requirements and the components to be mounted. 

There are several specific shapes and sizes of Din rails that are commonly used. TS35 (Top Hat) is the most common type of Din rail used and comes in standard sizes of 7.5 mm and 15 mm depth with 35 mm cross-width. This type is used for mounting IO controllers, circuit breakers and so on.

TS15 (Miniature Top Hat) comes in 15 mm width and 5.5 mm depth and is used for mounting smaller components such as junction boxes and function relays. TS32 (C-Section) have a heavy-duty C-section design used for applications that require extra support. TS (G-Type Section) have a heavy-duty G-shaped design used for panel-mounted components that require extra support.

Din rails systems allow components to simply snap and slide into place on the rail. They save space with tight configurations and provide a convenient site for bringing internal and external wiring circuits together. They result in a neat and well-organized component layout for easy access and all around safety.
