Art. Nr: 80035
Permanent magnet system Ø35x29mm electrically switchable
This magnet is permanently magnetic and loses its magnetic force when DC voltage is applied. Ideal for handling systems with increased safety requirements, as the load cannot fall in the event of a power failure and a short current pulse is sufficient to release the workpiece.

Areas of application
These magnets combine the advantages of permanent magnets with the flexibility of an electromagnet. They are used in numerous applications where reliable holding force is required without a continuous power supply, but where simple control to release the load is desired.
The way they work is based on the principle of magnetic flux control:
In its normal state, the permanent magnet generates a constant magnetic field that securely attracts metallic loads. A coil is wound around this permanent magnet, which also generates a magnetic field when a current flows through it. This opposing field reduces or neutralizes the magnetic field of the permanent magnet, causing the holding force to disappear or be greatly weakened. As a result, the load that was previously magnetically lifted is released.
This principle makes electromagnets particularly energy-efficient and safe, as they maintain their holding force even in the event of a power failure and the load does not accidentally fall. The following applications benefit from these properties:
- Material handling: In metal processing, mechanical engineering and warehouses, electromagnets are used to safely lift and transport metal plates and other ferrous workpieces and to set them down with a short current pulse. They are often used in lifting devices with increased safety requirements.
- Assembly and mechanical engineering: In production and assembly lines, these magnets help to securely hold workpieces without the need for mechanical clamping devices. They are ideal for applications in which sensitive surfaces need to be protected or the loads change frequently. During welding, milling or drilling, they provide a stable hold that can be quickly and controlled released.
- Automation technology: Electrically disconnectable permanent magnets are used in robotic systems to grip, transport and precisely place components. In automated production processes, they offer flexibility and safety because the magnetic field is permanently active and can be neutralized by a short current pulse. This also makes them a particularly energy-efficient alternative compared to other lifting devices.
