What are photoelectric sensors?
Photoelectric sensors, also known as photoyes, are electronic devices that are used to feel the presence or absence of an object or to measure Distance from the object, sometimes at the same time, for a number of applications. They use light that is usually in an infrared spectrum To the one that is sent by a light transmitter and is sometimes captured by a photoelectric receiver, but the second component is not always necessary. There are many different uses for different types of photoelectric sensors, for example, they are commonly used in automatic production, transport, Aviation technology, health industry and more. A specific machine that helps control its function or can also be built with a number of specialized features. An example of its use would be an installation line where it could be set to feel the presence of objects moving down the belt to calculate them, determine defects, determine the speed at which Items and more are produced. Another common place for a separate photoelectIic sensors are above the automatic doors to detect the presence of people I go in and open the door for them.
In high -speed production, photoelectric eyes are also used as a safety device that can turn off the machine automatically if the production stops or if they are Find out the presence of foreign objects or people around components that are dangerous or may cause serious disorders. Machine processing often includes Photoeyes that do not even allow the device to work at all if something blocks the light from the sensor.
Security of photoelectric sensors can run alarms if a person, animal or object exceeds their infrared beam.Fotoeyes can use photoelectrics A receiver that is located opposite the transmitter to form an infrared beam of light that triggers the alarm when the transmitter senses that Light does not reflect back. There are smoke alarmy, which are created using photoelectric sensors that work on the same principle. When the smoke enters Alarm, scatters the infrared beam and starts. Photoeyes can also be designed to work in the opposite way to release only When the light is left to travel from the transmitter to the receiver and back.
