What are modulated and non-modulated of Photomicro sensors Used for Industrial Equipment?
The following table shows the sensing method and characteristics for modulated and non-modulated light.
| Non-modulated | Modulated | ||
| 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 |
| External light interference |
Susceptibility to ambient light | Resistant to ambient light | |
