Limit switch (contactless, magnetic field-resistant):

The magnetic field-resistant limit switch is used to monitor and measure axial or radial mechanical movements and adjustments, e.g. in conjunction with EAS clutches.

Magnetic field-resistent proximity switches or those with welding strength are used where magnetic fields may influence the functioning of the proximity switch. For instance, in an area of strong magnetic coils and welding guns or welding electrodes with high welding currents.
