DIN Rail is a type of mounting commonly used for industrial control equipment inside equipment PCL racks and enclosures. There are many types of DIN Rail available, many of which conform to European (EN) and international (IEC) standards in order to match with the control equipment the rail is intended to secure.

### Types of DIN Rail

There are four common DIN Rail types that vary in length and size:

Top Hat (EN 50022) - This 35mm wide rail is also known as TS35 rail. The EN 50022 standard specifies both 7.5 mm and a 15 mm deep top hat rails, with slotted and unslotted versions.

Miniature Top Hat (EN 50045) – Also known as TS15 rail, this is a smaller variant of the standard Top Hat version, with a width of 15 mm x 5.5 mm depth.

C Section - Also called a TS-32 rail. The cross-section of C section mounting looks like the letter "C", the curved rails feature a symmetrical appearance. There are four popular types of C-Section DIN, the C20, C30, C40 and C50. The number corresponds with the height of the product in mm.

G Section (EN 50035) – This DIN mounting features a G-shaped cross-section with a curved asymmetrical appearance.

### Applications for Din Rails

DIN Rails are metal rails that are used when mounting electrical and industrial components in equipment racks, enclosure racks and panels, as well as control cabinets.

A typical mounting is made out of perforated cold rolled carbon based steel with a zinc-plated or chromated bright surface finish to prevent galvanic corrosion.

The steel fitments are highly versatile and can be used across a wide range of applications and fit a range of different equipment, regardless of the manufacturer. DIN rails save time, space and money by enabling the user to mount electrical components safely and securely, especially when wiring is included.

They are often used in applications such as:

- DIN rail terminal blocks
- Automation and control devices
- Power supplies
- Robotics
- Plug-in relays
- Panel meters
- I/O devices
- PLCs
- Contactors
