Din Rail

DIN rail are metal strips with standardized dimensions and edges designed for components to “clip” on. They are is used throughout the world to mount industrial equipment inside control cabinets, as well as in other applications. DIN rails are mounted directly on the wall or enclosure and then electrical industrial control products and components are secured to the rails. DIN rails are available in various depths, styles, shapes, and materials, with 35mm TS35 or “top hat” style in 7.5mm and 15mm channel depths being the most prevalent. 

Using a DIN rail mounting system provides several advantages including:

• Saving time (and money) since individual components clip on the rail instead of being mounted to the panel individually
• Saving space by allowing for tight, high-density configurations
• Facilitating organized panel layouts which improve the safety of working on the electrical components, as well as potentially reducing the amount of internal and external wiring needed

“DIN” is an acronym for Deutsches Institut für Normung, the German Institute of Standards/Standardization that developed the standards that were eventually adopted internationally by most manufacturers for designing mountable industrial control components such as circuit breakers, terminal blocks, relays, motor controllers, power supplies, drives, industrial radios and PLCs.
