Magnetic coils and actuation magnets are electromagnetic components for electromechanical and fluidic applications. Magnetic coils move the slider of valves as an anchor, actuation magnets with their own anchors are mainly used for positioning tasks, eg for interlocks. In the case of magnetic coils, classic coils with windings are to be distinguished around a solid body and air coils. Typical coil diameters are between 22 and 32 mm. Magnetic coils induce a magnetic field to attract the armature of the valve, which is guided in a guide tube through the coil and up to the core pole. In this arrangement, liquid or gaseous substances flow through the open valve. Due to a voltage drop in the coil, the stainless steel magnet armature moves back into the initial position, Whereby the valve is closed and the material flow is interrupted. Depending on the model, versions are available for high-temperature applications, with splash protection and for operation in hazardous areas. For actuation magnets, pulling and pressing must be distinguished. The movement is in each case triggered by an electromagnetic force and extends to a limited extent from the stroke start position to the stroke end position. The reset is effected either by way of an opposing second magnetic coil or by means of restoring mechanisms or customer-side restoring mechanisms, for example restoring springs. Depending on the model, the anchor was permanently in the approached position. Some operating magnets dampen the noise generated during operation. Reversing solenoids, folding position magnets and locking magnets are further actuation magnets. Magnetic coils and actuation magnets are used in the automotive sector, for example for variable valve control, as well as in fluidics for hydraulic and pneumatic applications. Actuating solenoids are used in linear slides, safety systems and locking systems.
