DIN Rails: A Versatile Mounting System

DIN rail is a standardized mounting solution that has become the backbone of modern electrical control panels and equipment racks. Originally developed by the German Institute for Standardization (Deutsches Institut für Normung, or DIN), these metal rails have evolved into an essential component across various industries. As an authorized distributor of Phoenix Contact DIN rails, Proax is committed to providing you with comprehensive knowledge about these versatile mounting systems.


What is DIN Rail?

DIN rail is a metal rail of a standardized type widely used for mounting control equipment in electrical panels and equipment racks. The term “DIN” refers to the German national standards organization that first standardized these rails. Today, DIN rails follow the European standard EN 60715 (formerly DIN EN 50022), which has been adopted worldwide.


The Purpose of DIN Rail

DIN rails serve as a universal mounting method for industrial control components, creating an organized, secure, and standardized system for:
