DIN Rails

DIN rails are standardised mounting systems commonly used for industrial control equipment inside equipment racks, enclosures, and panels. They are also utilised in various other applications such as electrical enclosures and automation systems. Various types of DIN rail conform to European (EN) and international (IEC) standards to ensure compatibility with the control equipment they secure.

Check out our comprehensive DIN rail guide to find out more about the types and applications available.

Types of DIN Rail Features

Perforated DIN Rail: Perforated DIN rails feature holes along the rail, providing flexibility for mounting components at various positions. These perforations allow for easy layout adjustments and customisation within control cabinets and enclosures.

Slotted DIN Rail: Slotted DIN rails have slots or grooves along the rail, enabling the use of specialised clips and fasteners for secure component mounting. These slots offer additional mounting options and can accommodate components with specific requirements while allowing better airflow.

Types of DIN Rail Structures

Top Hat DIN Rail

This 35mm wide rail, also known as TS35 rail, is named after its cross-section’s resemblance to a top hat. The EN 50022 standard specifies both 7.5 mm and 15 mm deep top hat rails, available in slotted and unslotted versions. Top hat DIN rails are widely used in industrial control panels and automation systems.

Miniature Top Hat DIN Rail

Also known as TS15 rail, this is a smaller variant of the standard top hat version, measuring 15 mm wide and 5.5 mm deep. Miniature top hat DIN rails are ideal for applications where space is limited or smaller components are used.

C-Section DIN Rail

C-section DIN rails have a C-shaped cross-section, providing a curved and symmetrical mounting surface. Known as TS-32 rails, there are four popular types of C-section DIN rail – C20, C30, C40, and C50 – where the number corresponds to the height in millimetres.

G-Section DIN Rail

This DIN mounting features a G-shaped cross-section with a curved asymmetrical appearance. G-section DIN rails are often used in specific applications where the asymmetrical shape offers advantages in mounting or component placement.

Types of DIN Rail Materials

• Stainless Steel DIN Rail: Stainless steel DIN rails offer excellent corrosion resistance, making them suitable for harsh environments or applications where hygiene is critical.
• Aluminium DIN Rail: Aluminium DIN rails are lightweight and offer good corrosion resistance. They are commonly used in applications where weight is a concern, such as in transportation or aerospace industries.
• Plastic DIN Rail: For cost-effectiveness, plastic DIN rails are a good option. They provide good insulation and are often used in applications where electrical isolation is important or where lighter-duty mounting is sufficient.

Types of DIN Rail Sizes

• **35mm DIN Rail: **35mm DIN rails are the most common size, providing ample space for mounting various industrial control components. They are widely used in control panels, automation systems, and electrical enclosures.
• **15mm DIN Rail: **A smaller alternative to 35mm DIN rails, 15mm DIN rails offer a space-saving solution for mounting smaller components or in tighter spaces.

DIN Rail Applications

DIN Rails are widely used for mounting electrical and industrial components in various settings, including equipment racks, enclosure, panels, and control cabinets.

A typical DIN rail is made from perforated cold-rolled carbon steel with a zinc-plated or chromated bright surface finish preventing corrosion. These steel fitments are highly versatile across a wide range of applications regardless of manufacturer compatibility.

DIN rails save time, space and money by enabling users to mount electrical components safely and securely, especially when wiring is included.

• Terminal Blocks: DIN rails are commonly used with DIN rail accessories to mount terminal blocks, providing a secure and organised platform for connecting wires and creating electrical circuits. Top hat DIN rails are often preferred for terminal block mounting due to their wide surface area and compatibility with various terminal block designs.
• **PLC Systems: **DIN rails are essential for mounting components in programmable logic controller (PLC) systems, providing a standardised and organised framework for housing PLCs, input and output modules, and other associated devices.
• Power Supplies: DIN rail mounting is frequently used for power supplies, allowing for easy installation and secure placement within control cabinets and enclosures.
• **Relays: **Relays, which are electrically operated switches, are often mounted on DIN rails to provide a secure and organised installation within control systems, such as energy management systems.
• Circuit Breaker: DIN rails provide a convenient and standardised method for mounting circuit breakers, ensuring their proper placement and protection within electrical panels and distribution boards.
• Sensors and Actuators: Sensors and actuators, essential components in automation systems, are also often mounted on DIN rails as they allow for firm and reliable placements.
• Robotics: DIN rails are used in robotics for mounting various control components, sensors, and actuators, creating a flexible and modular platform for building robotic systems.
• Contactors: Contactors, which are electrically controlled switches for high-current applications, are often mounted on DIN rails for easy integration into control systems.
• Panel Meters: Panel meters display various electrical parameters and need to be mounted in a way that allows for monitoring and control within electrical panels and industrial equipment. DIN rails are a convenient way to do so.
