What Is A Photoelectric Sensor?
Photoelectric sensors, also known as magic eyes, are used in many applications to detect obstacles or colors. It works by emitting light rays and detecting when light rays are obstructed by objects. The signal is sent to the control center for processing. As the “eye” of automatic production lines, plays an important role in industry. There are two types of optical sensors: Retro Reflective Sensors and Through-Beam Sensor, with the same detailed principle of operation.
Application Of Photoelectric Sensors
– Count products on conveyor belts.
– Check for defective products.
– Measure the thickness of the object’s surface.
– Detect stickers on packaging.
– Safety control when closing – opening the garage door.
– Turn the car wash faucet on – off.
– Detect people – objects passing through the door.
– Use for automatic parking lots.
– Check whether the detailed location of the machine is correct or not.
Advantages And Disadvantages Of Photoelectric Sensors
Advantages:
- Object detection without contact.
- Distance up to 100m, service life, and high accuracy, solid matter detection.
- Fast detection speed and adjustable sensitivity.
- Diverse supply sources
Disadvantages:
- The sensor may not work correctly when encountering dirt and dust.
- It is necessary to choose the type in accordance with the color and reflectivity of the surface to ensure accuracy.
- Choosing the right optical sensor also requires experience and understanding of each specific application.
