Din Rail

Narrow Your Results By

At Control Design Supply, we provide a wide selection of DIN rail for mounting industrial control components in a secure, organized, and efficient way. DIN rail is the backbone of modern control panels—used to mount circuit breakers, power supplies, relays, terminal blocks, and more. Whether you need standard slotted or solid (unslotted) rail, we have options to meet your specifications.

Below are the two most common forms of standard din rail that you may see.

What is DIN Rail?

DIN rail is a standardized metal rail used to mount electrical and industrial automation components within enclosures and control cabinets. Originally developed in Germany (hence "DIN," which stands for Deutsches Institut für Normung), it has become a global standard for modular panel assembly.

The most common type is 35mm wide DIN rail, often referred to as “top hat” rail due to its profile. It comes in both slotted (for easier component positioning and grounding) and unslotted (for clean appearance or specific mounting requirements) variations. The rail is typically made from zinc-plated steel, aluminum, or stainless steel, depending on the application and environment.

Why Use DIN Rail in Your Control Panels?

DIN rail provides several important advantages:

Universal compatibility – Most industrial components are designed for DIN rail mounting.
Fast, tool-free installation – Many devices simply clip or snap onto the rail.
Standardization – Using DIN rail promotes consistent layouts and easy servicing.
Space efficiency – Vertical and horizontal mounting options maximize enclosure space.

Whether you're working on a new automation panel or modifying an existing one, DIN rail helps you build smarter, cleaner, and faster.

Custom-Cut DIN Rail Available

At Control Design Supply, we understand that not every project uses standard 2-meter DIN rail lengths. That’s why we offer custom cutting services to provide DIN rail in the exact lengths you need. Whether you're working with tight space constraints in a compact enclosure or preparing pre-sized sections for streamlined production, we can cut your DIN rail to your specifications. Just let us know your required lengths when you request a quote, and we’ll take care of the rest—saving you time on the job site and reducing material waste.

Applications for DIN Rail

DIN rail is used in a wide range of industries and environments, including:

Industrial automation
Process control
Electrical distribution
Building automation
Renewable energy systems
OEM control panels
