Inductive Proximity switches are used to identify the presence of metal objects, speed measurements, position sensing, counting etc.,without any physical contact with the, objects. It enhances the durability of the Switch and ensures maintenance free work.
Inductive Proximity switch generates high Frequency alternating field at the active face by the oscillator circuit. When any metal object is brought into the field it causes oscillation to stop. Hence the demodulated voltage feeding the trigger disappears.
DC Inductive Proximity Switches:
For DC Switches the trigger operates rapidly when oscillation stops. This trigger switches the O/P, NPN/PNP transistor to drive an electronic circuit or relay.
AC Inductive Proximity Switches:
For AC switches a thyristor is triggered when oscillation stops. This thyristor is connected in series with a bridge and this series combination is connected to the AC Load.
