DIN Rail Mounting Adapters


Single-Clip Adapters for DIN 3 Rails	Single-Clip Adapters for DIN 1 Rails

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

Spring-Clip Adapters for DIN 3 Rails

Mount items not designed for DIN rail by attaching them to these adapters. Adapters clip onto the rail.

For large items that need more stability, use multiple adapters or choose an adapter with more than one mounting hole.

12 Mounting Holes and 30 Mounting Holes—Adapters with 12 and with 30 mounting holes have a panel for positioning multiple items together in whatever arrangement you need.

DIN Rail Spacers

For DIN 3

Rails

For DIN

1 Rails

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.

Snap On (For DIN 3 Rails)

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

Screw On—Screw-on stops wedge in place against the DIN rail as you tighten the screw for a more secure hold than snap-on stops.

Snap On—Snap-on stops clip onto the DIN rail with no special tools required, so they’re quicker to install and remove than screw-on stops.

DIN Rail Group Markers—DIN rail group markers mount onto stops—label them for easy identification.

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 and prevent them from overheating. 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 3	DIN 1	DIN 2	DIN 3 Rails with Bracket	DIN 3 Rails with Angled Bracket

Mount terminal blocks, power supplies, relays, and other control and distribution devices on walls and other flat surfaces and in enclosures.

DIN Rails with Bracket—DIN rails with a bracket create extra space behind them to accommodate bulky items.

DIN Rails with Angled Bracket—DIN rails with an angled bracket are tilted, letting you fit more of them into a vertical space. For easy access, position high-mounted devices so they’re tilted downwards and low-mounted devices so they’re tilted upwards.

DIN Rails with Centerline—On DIN rails without mounting holes, drill holes where you need them. Rails with a centerline guide where you should drill.

DIN 3—DIN 3 is the most commonly used rail.

DIN Rail Mounting Brackets


Angled	Straight	Angled	Straight

Use these brackets for extra mounting space behind DIN rail to accommodate wiring and bulky items. Brackets with multiple DIN rail mounting holes hold several DIN rails on one set of brackets, so you don’t need to drill as many holes in your enclosure.

DIN-Rail-Mount Hook and Loop Straps

Clip to DIN rail to route and organize wire, cable, and hose. These straps are often paired with DIN 3 rail, 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.

Adhesive-Back DIN Rails


1 lb. Capacity	16 1/2 lb. Capacity

Stick this DIN rail in any enclosure to mount components without making screw holes that might leak. The adhesive backing and short length let you install these in tight spaces where a screwdriver wouldn’t fit. Adhesive reaches full capacity after 24 hours.

UL 94 V-0—DIN rails meet UL 94 V-0, so if they catch fire, they’ll self-extinguish within 10 seconds and won’t spread the fire by dripping.
