Short Circuit Protected Magnetic Field Sensors come in weld-field immune version for welding applications. These Magnetic Field Sensors are suited for piston position detection in pneumatic cylinders. These Magnetic Field Sensors can detect a permanent magnet attached to the piston through the aluminium wall of the cylinder as magnetic fields can permeate non-magnetizable metals. Short Circuit Protected Magnetic Field Sensors are capable of detecting permanent magnets of various field strengths on all common cylinder types.
