How to identify the detectable range of various photoelectric sensors? 2

3. Reflective photoelectric sensor:

This type of sensor sends a beam of light and detects the light reflected back from the target object. The detectable range depends on the intensity of the light source, the reflection performance of the target object, and the sensitivity of the receiver. Manufacturers typically provide a range of data for detecting distance and reflecting object types.diode

4. Interferometric photoelectric sensor:

Interferometric sensors are capable of measuring very fine distance changes, and they typically use lasers as light sources. The detection range can be determined by the coherence length and interference mode of the laser.diode

5. Fiber optic sensor:

This type of sensor uses optical fibers to guide light to distant or small space targets. The detection range depends on the type, length, and bending degree of the optical fiber, as well as the optoelectronic components used in conjunction with it.diode
