Disadvantages of Photoelectric Sensor
- It offers various sensing ranges but they may not be suitable for applications that requires extremely long distance detection .
- Interference of other sensors operating at same frequencies can disrupt the the operation of photoelectric sensors.
- Proper alignment of photoelectric sensors is necessary for optimal performance. In through beam sensor proper alignment between emitter and receiver is necessary , which can be time consuming .
- Reflective and diffuse reflective sensors can be sensitive to the surface properties of objects that can be detected .
- They require periodic maintenance for optimal performance .
Photoelectric Sensor
A photoelectric sensor is a type of sensor used to detect the presence or absence of objects, as well as to measure distance, based on the principle of light reflection or interruption. It typically consists of a light transmitter and a receiver, which are positioned opposite each other with a gap between them.
