Working Principle

The GRL18S-E1336 optical sensor operates on the principle of photoelectric detection. The sensor comprises of an array of infrared LEDs (illuminators) and two photodetectors. When the LED is turned on, it emits a beam of infrared light that is directed towards the object being detected. The beam is then reflected back to the sensor by the object and is received by the photodetectors. The photodetector then changes the analog signal into a digital signal, which is then processed by the built-in circuit. Depending on the intensity of the reflected light, the GRL18S-E1336 can detect the presence of an object up to a distance of 18 mm.

Conclusion

The GRL18S-E1336 optical sensor is a powerful and reliable tool for industrial automation and robotic applications. It features a detection range up to 18 mm and an operating range of 1 V DC to 24 V DC. Its photoelectric detection feature can be used for motion sensing, object detection, presence detection, door openers, barcode reading and much more.
