Description:
WORKING PRINCIPAL
AN INDUCTIVE ALTERNATING r.f. FIELD IS DEVELOPED AT THE FRONT OF THE SENSING SURFACE OF THE PROXIMITY SWITCH. THIS FIELD IS GENERATED BY THE RESONANT CIRCUIT COIL OF THE OSCILLATOR.                     
ENERGY IS ABSORBED WHEN A METAL PIECE IS BROUGHT INTO THE r.f. FIELD NEAR THE SENSING SURFACE, CAUSING OSCILLATION TO STOP. HENCE THE DEMODULATED VOLTAGE FEEDING THE TRIGGER DISAPPEARS.

FOR DC SWITCHES
THE TRIGGER OPERATES RAPIDLY WHEN OSCILLATION STOPS AND THIS TRIGGER SWITCHES THE OUTPUT TRANSISTER, WHICH CAN BE EITHER NPN OR PNP TO DRIVE AN ELECTRONIC CIRCUIT OR RELAY.
FOR AC SWITCHES
THYRISTOR IS TRIGGERED WHEN OSCILLATION STOPS DUE TO THE PRESENCE OF METAL . THIS THYRISTOR IS CONNECTED IN SERIES WITH A BRIDGE AND THIS SERIES COMBINATION IS CONNECTED TO THE AC LOAD.
ADVANTAGES OF PROXIMITY SWITCHES
THESE SWITCHES CAN BE USED ANYWHERE WHERE EXTREME CONDITIONS EXIST, e.g.
1         WITH LUBRICANTS AND CUTTING OILS
2         UNDER VIBRATION
3         ENVIRONMENTS WHERE WATER AND STEAM ARE PRESENT
4         DUSTY ENVIRONMENTS, etc.

APPLICATIONS 
INDUCTIVE PROXIMITY SWITCHES OR SENSORS ARE PRIMARILY USED WHEN THE OBJECT TO BE SENSED IS METALLIC,.  SOME APPLICATIONS OF INDUCTIVE PROXIMITY SWITCHES ARE
MACHINE TOOLS, TEXTILE,  SUGAR, CEMENT, AUTOMOBILE INDUSTRIES AND MANY MORE.
