Inductive Proximity Sensors are used for non-contact metal sensing. Being contactless sensors these can be used for position sensing, speed measurement, counting, etc. These inductive proximity sensors can be used in extreme conditions, such as oily, dusty, corrosive environment. Inductive Proximity Sensors are used from automobile industries to steel industries, from CNC/NC machines to material handling equipments, process automation, conveyor systems, packaging machines.

These inductive sensor DC types are designed to work as solid state DC limit switches. The Sensors are connected directly in series with a load and have a bridge rectifier so they are not polarity conscious. The circuit is such that, when in off state, it allows very low current to flow through the load. However, a output load (such as relay) should be chosen, considering the voltage drop across the switch in the ON state. These sensors find wide application in electrical control circuits and PLC''s.

Switch Type
Inductive
Inductive sensor with analog output works in similar way as standard 3 wire DC Inductive Sensors. When a metal target comes in vicinity of the sensor, energy is drawn from the oscillator. This energy loss is in proportional with the distance between sensor and the target; which is converted in analog signal. The analog signal is made linear and then amplified to give 0-10 V output.
