These electronic magnetic sensors operate on the basis of the Hall effect. This means that they generate an output signal when their sensitive area is affected by a magnetic field produced by a permanent magnet. Just like inductive sensors, the output signal is very precise, repeatable and fast, but they offer the added benefit of very high operating distances and reduced mechanical dimensions, this type of performance is a restricted to reed-type magnetic sensors, however, such devices are susceptible to vibrations and mechanical shocks that do not affect Hall-effect electronic magnetic sensors. The sensors are supplied with a M12x1 cylindrical case or parallelepiped case (see technical features), pluggable or hard-wired connection option and indicator led, NPN and PNP output logic with normally open or closed contact in the monostable version, and NPN+PNP output logic with normally open contact in the bistable version. MONOSTABLE MODELS — If the sensor sensitive area is affected by a static magnetic field, irrespective of polarity, the output changes state, immediately reverting to the initial state when the field is removed. BISTABLE MODELS — If the sensitive area of the sensor is affected by a North polarity static magnetic field, the output assumes the closed state, remaining in this state until the field is replaced by a South polarity field, whereupon the output returns to the open state.
