Inductive Proximity
Switches

Operating Principle Of Inductive Proximity Switches
Proximity sensors are the most common and available switches affordable switches for non contact object detection. The most commonly used proximity sensors are the inductive type which generates an electromagnetic field to sense metal objects passing close to the sensing free and generates the output signal.
The LC Oscillator circuit generates the electromagnetic field over the active face , energy is drawn from oscillator resulting damping of the oscillator. This change is detected by electronic circuit and is converted into an effective output signal.

Application
For position sensing in Automation. •Automobile
•Food
•Pharmaceuticals
•Steel
•Cement
•Engineering Industries.

Sensing Distance
The sensing distance is the distance between the target and sensing face at which the switch operates. The sensing distance is usually specified considering M.S. as sensing objects.
