Photoelectric sensors are sensors which are used to detect colour and distance of an object. These sensors are position sensor that uses light emitting diodes as the light source. The sensor works on the principle of light being emitted from the sensor onto an object, following which the light is reflected back onto the photoelectric sensor again. Based on the time it took for the light beam to hit the object and be reflected back, the sensor is able to estimate the distance the object is away from it. Photoelectric sensors are increasingly being used across a number of industries some of which include the construction and automotive industries. Photoelectric sensors are increasingly being used in the industrial sector where they are used for detecting position misalignments. The sensors are placed at predetermined locations through which the placement of a product can be measured and see if it has been placed properly or not. Based on the data from the sensors, the information is tra...
