Optical sensors enable detection of light and radio signals in order to measure levels, detect objects or analyse materials. Among these sensors, the E3G-R17-G is a general-purpose photoelectric sensor which is mainly used in industrial applications. This article focuses on explaining its application fields, and its working principles.

Application Fields

The E3G-R17-G photoelectric sensor is a good choice for medium-range applications as it has an operating range of 0 to 10m. It is suitable for sorting, position detection, object detection and detection of objects over long distances. It is also suitable for detecting fabric of textiles and other materials. Furthermore, this photoelectric sensor can also be used for counting and inspecting, as the E3G-R17-G has a high-level sensitivity and accuracy.

Working Principle

The working principle of the E3G-R17-G photoelectric sensor is quite simple and relies on an infrared light beam being directed towards the object being detected, which in turn reflects the light back towards the sensor. The reception of the light signal is then transformed into an electrical signal and detected. The output of the sensor is a high-level switch signal which can be used to control the system.

The basic components of the E3G-R17-Gphotoelectric sensor are the light source, receiver, amplifier and output. The light source consists of an infrared LED which produces the infrared light beam, while the receiver comprises of a light-sensitive diode. These two parts form an optical path which is then directed at the target to detect. The amplifier receives the received signal and amplifies it, and finally the output is a switch signal which is sent to the control system, usually a PLC.

The E3G-R17-G photoelectric sensor can be adjusted to a desired sensitivity, making it suitable for a wide range of applications. This adjustment process involves setting the correct distance between the light source and the receiver. By adjusting the distance between these two components, the sensing range of the photoelectric sensor can be altered. The sensitivity of the sensor can also be adjusted by varying the power supply. In addition to these adjustments, the operating conditions, such as the environment, temperature and air pressure, should also be taken into consideration.

Conclusion

In conclusion, the E3G-R17-G photoelectric sensor is a useful general-purpose sensor with a medium-range operating range of 0 to 10m. It is suitable for applications such as object detection, position detection, counting and inspection. Its working principle relies on the reflection of an infrared light beam from the object being detected. The reception of the light is then transformed into an electrical signal which is sent to the control system. The sensitivity and accuracy of the E3G-R17-G can be adjusted by varying the standing distance between the light source and receiver, and the power supply.
