General Description

These sturdy steel DIN rail mounting brackets are useful for mounting a wide variety of devices onto standard 35 mm DIN rail. They feature a flat mounting surface and pre-drilled mounting holes, which, depending on the model, are threaded (M4 x 0.7mm) and/or unthreaded. These brackets very easily attach and detach from a DIN rail while maintaining high rigidty and load capacity: the bracket latches onto both the top and bottom lips of the rail with the fixed (non spring-loaded) end of the bracket on the top of the rail to bear the weight of its device.

Several models are available. They vary in size, mounting hole style, ways in which they can be detached from a DIN rail, and amount of rail clearance. The differences between each model can be seen below:

We also offer a Right Angle version which can save significant DIN rail space by mounting devices perpendicular to the rail.

Rail Clearance / Installation & Removal Method

Clips are offered in two different versions, which impacts both how it can be installed/removed, as well as its rigidity on the rail:

Lift & Pivot (More Rail Clearance): The lower bumper on Lift & Pivot clips has enough spacing from the bottom of the DIN rail that the clip can be lifted/tilted on and off the rail without needing to depress the Latch tab. This provides easy installation and removal from the DIN rail, even if the Latch is hard to reach behind your device, but also means the clip may be able to tilt sideways under heavy side loads.

Latch Release (Tighter Rail Clearance): The bumper on Latch Release clips has a tighter spacing to the bottom of the DIN rail. This constrains the movement/tilting of the clip, making it more rigid under side loads. However, it also means that you must slide the Latch Release tab in order to install or remove these clips from the DIN rail.

Brackets with a smaller bumper have more space between the bracket and the DIN rail.

Brackets with a wider bumper have less space between the bracket and the DIN rail.

The tighter rail clearance of the Latch Release version restricts movement of the bracket on the rail, making the assembly more rigid for unusual side loading or rotational forces. This can be helpful, for example, when dealing with arrangements that have unusually stiff cables.

More rail clearance increases the movement of the bracket on the rail, but allows for easier removal.

More rail clearance is less likely to keep the bracket from twisting on the rail.

Tighter rail clearance keeps the bracket in place, even when unusually stiff cables are involved in the assembly.

Removal from a Rail

Removing Lift & Pivot Clips: DINM21, DINM22, DINM23, DINM23T3, DINM23U40, DINM24

Typically the simplest method to remove the Lift & Pivot clips is to lift up on the mounted device, pivot the top of the device out away from the rail, and lower the entire device off the rail. This technique is possible because of the larger amount of rail clearance and does not require access to the release handle, which makes this method easier, especially if a bulky device is mounted to the clip and is blocking easy access to the latch tabs. However, you can also use the Latch Release method to remove these brackets if desired.

Removing Latch Release Clips: DINM20, DINM23LR

To remove Latch Release brackets from a DIN rail, either pull the release handle from the bottom edge of the bracket (see our lanyards, sold separately), or push the handle down from the top edge of the bracket. This releases the sliding hooks that grip the bottom of the rail and allows the bottom edge of the bracket to swing out away from the DIN rail. The entire bracket can then be lifted off the DIN rail.

Because these models have tighter rail clearance, the Latch Release handle must be actuated in order for the bracket to be able to move far enough away from the rail to detach. For this reason, the "lift and pivot" method will not work.

Use the release handle to remove a Latch Release bracket from the DIN rail.

Mounting Hole Style

DINM20, DINM23U40, DINM24

The DINM20 and DINM23U40 have two and the DINM24 has four unthreaded 4mm diameter mounting holes. The holes in this bracket can accommodate M4 (M4 x 0.7mm) machine screws, #6 machine screws, or #6 sheet metal screws. Please note that the small head size M4 hardware (sold separately below) will be needed in order to work well with the DINM20 and DINM23U40 clips if the screw heads are located on the back side of the clips.

DINM23T3

The DINM23T3 contains M3 threaded (M3 x 0.5mm) mounting holes. Winford does not yet sell screws for these clips, but they are available from many hardware vendors.

DINM21, DINM22, DINM23, DINM23LR, DINM24

The DINM21, DINM22, DINM23, DINM23LR, and DINM24 contain M4 threaded (M4 x 0.7mm) mounting holes. Winford offers M4 machine screws (sold separately below) that work well with these clips.
