What is DIN rail?

This is a metal rail that is commonly used when installing relays, timers, sequencers, breakers, and other devices used in control panels.
DIN is the abbreviation for German Industrial Standards (official name: Deutsches Institutfur Normung), which is equivalent to Japan’s JIS (Japanese Industrial Standards). It is also called the international standard “IEC rail.”

How to use DIN rails

The rail itself has pre-drilled mounting holes, making it easier to attach and remove than if each part were attached with screws, reducing construction and maintenance labor.

Material and size

The material is aluminum, and the DIN rails that are often used inside control panels are 35 mm wide.
In addition, since it follows the standard, the dimensions are uniform across DIN rails from all manufacturers.
