Industrial Demagnetizers - 3 options

Blue Tabletop demagnetizer


Great choice of tabletop systems. Many different sizes are available. They can also be used under or over a conveyor belt.



We offer 2 different types of tunnels (aka loop demagnetizer), the DT and T series. Each have a different form and size option.

We manufacture customized systems. Including automated conveyors, Low frequency generators, sensors etc...


How does a demagnetizer work?
In order to demagnetize a component, remove magnetism, it is necessary to subject the part to an alternating and decreasing magnetic field.
The reduction of the field can be done in the following ways:

1. Automatically, using a programed impulse control unit by Braillon Magnetics. The part does not need to be moving for this option.

2. By moving the part slowly at a constant speed over the surface of a demagnetizer tabletop or through tunnel demagnetizer.

In order to remove magnetism from a larger thicker part, you will get better results when adding a low frequency generator to one of our industrial demagnetizer systems.

Tabletop options

Blue Tabletop demagnetizer


The Reinforced tabletop Demagnetizer type DP is Heavy duty. Super efficient, automatic adjustment of magnetic field intensity depending on workpieces. Great for parts 2 inches thick and under. For bigger workpieces, we recommend tunnel demagnetizer.



Unlike the DP Series which has 100% duty cycle. This light duty demagnetizer is great for one off's and non production use. However the DM series is a great economical option for many of our customers. Just grab your part and waive it back an forth over the demagnetizer at slow and constant speed.

Tunnel options


T Series

The Tunnel Demagnetizer T series are Heavy duty and Waterproof. Designed for 100% duty cycle. The Coil is encapsulated in a high performance epoxy resin. Sizes start at 180x180mm up to 600x420mm mouth opening.

Tunnel demagnetizer DT series

DT Series

The Tunnel Loop Demagnetizer type DT is Heavy duty Waterproof. Designed for continuous operation cycle. Usually installed on conveyor or or table. Sizes available up to a 150x100mm to 750x550 opening.

Custom options


Low frequency generator

A low frequency generator can be added to our demagnetizers. This option will help you to reach a deep demagnetization cycle for those thicker, harder parts or for bulk demagnetizing.

Custom Conveyors

Different size parts call for different types of conveyors. We can customize a demagnetizer system with automated belts or rollers. From light to heavy duty options.


Impulse control unit

Use an impulse control unit to program the demagnetizer with an alternating and decreasing magnetic field. This allows you to simply place your part in the demagnetizer without having to move the part via conveyor. Just run the program.

A demagnetizer will  usually come in form of a tunnel (also known as a loop demagnetizer), tabletop or a handheld wand. Simply put, the job of a demagnetizer is to remove magnetism from a part through the process of demagnetization. To do so, the demagnetizer coil must induce an alternating and decreasing magnetic field into the part. This can be done two different ways:

1. Moving the part through a demagnetizer tabletop or tunnel, at a constant & slow speed.

2. Placing part in a demagnetizer that has a programable alternating field via an impulse control unit.

Many customers have residual magnetism after machining there parts on magnetic chuck or other industrial processes. It is essential that the parts being demagnetized be moved over or through the demagnetizer at a slow and constant speed. In order to avoid incomplete demagnetization, the parts must be moved away as far as possible from the demagnetizing device at the end of the operation.

Also, the power supply must not be interrupted during the cycle, as it will not allow for a full and proper demagnetization cycle. For large, bulky components, the operation may have to be repeated several times. The use of a low frequency generator can also be very helpful for large, thick and hard parts. 

The length of the components that are to be demagnetized is not very important. It is only necessary that they be narrower than the tabletop demagnetizer or the opening of the tunnel or loop demagnetizer.

In order to demagnetize parts which are wider than the standard platen widths it is possible to mount several demagnetizers side by side. However, whether to select a tabletop or a tunnel will depend on the thickness of the component.
To demagnetize bulky components, we recommended the use of a tunnel demagnetizer which acts upon the whole of these parts, from the periphery to the very heart of the material.

Continuous duty means a low induction and field intensity. Intermittent duty means high induction and intensity; this duty is defined in percentage of the total cycle time.
Example: Duty 25 %: on 1 mn + off 3 mn = cycle 4 mn.
