Hall effect magnetic sensor SHC - 12L series

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.
