What are modulated and non-modulated of Photomicrosensors Used for Industrial Equipment?
The following table shows the sensing method and characteristics for modulated and non-modulated light.
|Sensing method||Method used to detect light steadily|
emitted by the emitter element
|Method used to detect light emitted in|
pulses by the emitter element
|Characteristic||Cost||Lower than modulated models||Higher than non-modulated models|
|Susceptibility to ambient light||Resistant to ambient light|
