Hand demagnetizer RO
Some materials hold residual magnetism after exposure to a magnetic field - the amount depends on the size of the workpiece and the type of material. To eliminate this undesirable residual magnetism, objects must be exposed to an alternating magnetic field that eliminates it to the lowest possible value.
For large parts and workpieces, the lightweight HD Series Handheld Demagnetizer is easy to operate and easy to carry. We offer a manual demagnetizer in two versions depending on the thickness and dimensions of the workpiece that needs to be demagnetized. HD2 is designed for larger and thicker workpieces or tools.
Advantages of a manual demagnetizer
- Compact dimensions and mobility
- High demagnetizing power
- Lightweight plastic construction with a large handle
- Switch button for easy operation
- Overheat protection
- Recommended duty cycle 20%
- Power 3m cable with plug

We recommend the table demagnetizer SO for quick manual demagnetization of tools and flat or small cylindrical workpieces handled by hand; the hand demagnetizer RO is the right choice where the workpiece cannot be brought to the unit — such as moulds, bearings or parts of machinery. For batch demagnetization in automated production lines, we supply the tunnel demagnetizer TO, or the TOSD with an integrated belt conveyor for continuous operation.
Table and hand demagnetizers generate a demagnetizing field of up to 40 mm above the working surface; the table model DEM-4 Easy Logic handles even large, solid workpieces within this range thanks to its automatic power regulation. The tunnel demagnetizers TO and TOSD remove residual magnetism using a gradually decreasing alternating field; for materials with high hardness we supply a special version of the unit.
Yes, we supply the tunnel demagnetizers TO and TOSD in various sizes and supply voltages so they can be built directly into existing conveyor systems. The compact design of both units allows installation even in space-constrained production environments; we will assess the installation site and propose the optimal configuration.
The key parameter for effective tunnel demagnetization is maintaining the optimal throughput speed of approximately 0.2 m/s. The TOSD model has the conveyor directly integrated in the unit and maintains this speed automatically; for the tunnel demagnetizer TO, the correct speed depends on the settings of the existing conveyor system.
Standard tunnel demagnetizers TO and TOSD operate using a gradually decreasing alternating current in electromagnetic coils; for workpieces with high material hardness we offer a special version of the unit with adapted output. The SO series table models are equipped with a dual coil with unlimited duty cycle and automatic regulation that adjusts to the shape and size of the workpiece.
We offer the table demagnetizer SO in four variants: DM 3 (250 × 180 mm), DM 4 (280 × 266 mm), DM 5 (400 × 306 mm) and DEM-4 Easy Logic (280 × 280 mm) — all rated 220 V with a power consumption of 352 W. The choice of model depends on the dimensions of the workpieces to be demagnetized; we will recommend the right type for your application.
Demagnetizers are used primarily in metalworking, mechanical engineering and foundries, where residual magnetism interferes with machining or assembly of components such as moulds, bearings and shafts. Table and hand demagnetizers are designed for demagnetizing tools and workpieces in the workshop, while tunnel units handle batch demagnetization of mass-produced components in automated lines.
