Description
A photoelectric sensor, also known as a photoelectric switch or photo sensor, is a type of sensor that uses light to detect the presence, absence, or position of an object. It operates based on the principles of light emission, transmission, and reception to determine the state of the object being sensed. Photoelectric sensors are widely used in industrial automation, robotics, packaging, and other applications for object detection, counting, positioning, and more. Photoelectric sensors emit light usually in the form of infrared or visible light from a light source, such as an LED light-emitting diode. Detection Modes:
Through-Beam Opposed Mode: The emitter and receiver are placed opposite each other, and the presence of an object between them interrupts the light beam.
Reflective Mode: Both the emitter and receiver are housed in the same unit, and the light reflects off a nearby surface. An object s presence affects the reflected light.
Diffuse Reflective Mode: The emitter and receiver are housed in the same unit, and the object reflects the emitted light back to the receiver. Photoelectric sensors are versatile and adaptable to a wide range of applications. When selecting a photoelectric sensor, factors such as the type of detection mode, sensing range, light source, and environmental conditions should be considered to ensure accurate and reliable performance in the intended application. Sensors have several types of screw threads M12, M18 and M30
