3 Rails

Mount terminal blocks, relays, and other devices onto flat surfaces. These rails are often used in electrical enclosures, server racks, and equipment cabinets.

DIN Rails with Bracket—Create extra space between the rail and the mounting surface to fit bulky devices or route wires.

DIN Rails with Angled Bracket—Mount equipment at an angle while adding space behind it. The tilted rail makes labels and displays easier to view, especially in crowded enclosures.

Centerline—Keep mounting holes lined up as you drill along these rails.

Drill-Your-Own DIN Rails—Add mounting holes only where you need them.

304 Stainless Steel—The best choice for equipment that’s regularly washed down. These rails resist corrosion from water and mild chemicals.

Aluminum—Lightweight and corrosion resistant. These rails hold up in wet environments almost as well as stainless steel, but they’re not as strong.

Zinc-Plated Steel—Strong and durable. These rails have zinc plating to protect them from occasional exposure to moisture.

DIN Rail Trade Size—We gave each type of rail a trade size to help you quickly find compatible parts. DIN 3 is the most common type of rail—it's also called top hat or standard rail. DIN 2 is a smaller version of DIN 3, so it's also known as mini rail. DIN 1 is also known as G-section rail.

DIN Rail Mounting Adapters


	Single-Clip Adapters for DIN 3 Rails	Double-Clip Adapters for DIN 3 Rails	Panel-Clip Adapters for DIN 3 Rails	Spring-Clip Adapters for DIN 3 Rails

Mount items that aren’t designed for DIN rails with these adapters. They clip onto the rail for a secure hold. For large items that need more stability, use multiple adapters or choose an adapter with more than one mounting hole.

Panel-Clip Adapters—Designed for positioning multiple items together, these adapters have several mounting holes in a grid pattern

Spring-Clip Adapters—Load-rated for holding heavy equipment.

For DIN Rail Trade Size—We gave each type of rail a trade size to help you quickly find compatible parts. DIN 3 is the most common type of rail—it's also called top hat or standard rail. DIN 2 is a smaller version of DIN 3, so it's also known as mini rail. DIN 1 is also known as G-section rail.

DIN Rail Stops


Screw On Rail Stops for DIN 3 Rails	Snap On Rail Stops for DIN 3 Rails	Screw On Rail Stops for DIN 1 or DIN 3 Rails

Stop terminal blocks, relays, and other components from sliding along DIN rails.

Screw On—As you tighten the screw, these stops wedge into place on the DIN rail for a more secure hold than snap-on stops.

Snap On—Press these stops against a DIN rail and they snap into place. Since you don’t need tools, they’re faster to install or remove than screw-on stops.

Group Markers—Label these markers and attach them to stops for easy identification.

DIN Rail Mounting Brackets


	Angled	Straight

Create extra space between your DIN rail and the mounting surface to route wires or fit bulky devices.

Angled—Tilt your rail at an angle while adding space behind it. These brackets make labels and displays easier to view, especially in crowded enclosures.

DIN Rail Spacers

Create space between components mounted on DIN rails for cooling, installing wire, and organizing electrical panels and cabinets. These spacers slide along DIN rails so you can shift terminal blocks, relays, and other parts without having to remove the spacers.

Magnetic-Back DIN Rails

Quick to install and easy to reposition, these rails mount to steel enclosures with a strong magnet. Since you don’t need to drill holes to install them, they help you avoid leaks in liquid-tight enclosures. They’re also good for tight spaces where a screwdriver won’t fit.

DIN Rail Mounting Adapters for Development Boards

Protect development boards from dust, water, and debris by mounting them to DIN rails inside control cabinets. These adapters have an open-air design to keep boards cool. They attach perpendicularly to DIN rails, taking up less space in your setup. Use the included cable ties to secure your cords to the mount and keep connections free from strain.

Adapters with adjustable standoffs have slots to accommodate a range of development board sizes. This means you won’t need a new mount if you switch to a different board. However, they take more time and hardware to set up than adapters without adjustable standoffs.

DIN-Rail-Mount Hook and Loop Straps

Clip these straps to DIN rails to route and organize wire, cable, and hose. They're made to fit DIN 3 rails, which are the most common size. All meet UL 94 V-0, meaning they quickly self-extinguish, so they're a good choice for hot and poorly ventilated places such as server rooms.

Straps with Buckle— For an extra-tight hold, cinch these straps down with the built-in buckle.

Clip On

Flammability Rating—Straps with a UL or FAA flammability rating burn slowly or self-extinguish to reduce the risk of fire spreading.

DIN Rail Cutters

Pull the lever on these cutters to make smooth cuts in steel and aluminum DIN rails without leaving a bur. To cut the same length over and over, slide the stop along the ruler and clamp in place. Cutters mount to your workbench.

12 × 6.4 mm Hole Punch—Cutters with a hole punch are used to add slots anywhere along a rail. You can position the die to cut horizontal or vertical holes.

Cable Holders for DIN Rails


C-Shape Clips with Bottom or Top Entry	C-Shape Clips with Side Entry	Interlocking Clips with Side Entry

Slide these holders onto DIN rails to route and organize your cables. They’re often used in server racks and equipment cabinets. Since they mount without adhesive or screws, you can move them anywhere along the rail.

C-Shape Clips—Designed for frequent setup changes, these clips make it easy to add, move, or remove cables.

Interlocking Clips—Hold cables more securely than C-shape clips.
