E3G-ML79-US

Optical sensors are among the most widely used industrial sensors in the world, for the purpose of measuring, monitoring and controlling a variety of processes. In this article, the E3G-ML79-US will be discussed in terms of its application field and working principle, so that readers can gain a better understanding of the series of sensors.

Application Field

The E3G-ML79-US optical sensor is a highly sensitive series of optical sensors designed specifically for use in industrial settings. It features a range of sensing modes, including through-beam, retro-reflective and background suppression. It is capable of detecting small objects, such as tiny screws or even smoke particles, to monitor objects in motion, as well as accurately measure distances between objects. The sensor can also be used for presence detection, to ensure that certain objects or areas are being monitored at all times. The sensor is small and compact, yet its sensing range can reach up to 500 mm.

Working Principle

The working principle of the E3G-ML79-US optical sensor lies in its ability to detect a wide range of light sources. Its internal optics consist of a light-emitting diode (LED) and a phototransistor. When the LED is activated, it emits a narrow beam of light, which is then picked up by the phototransistor. Depending on the type of sensing mode it is set to, the sensor will detect the presence or absence of an object within its sensing range. Through-beam mode, for example, produces an optical beam between its two sensor elements, and objects passing through the beam will cause the phototransistor to detect a change in light intensity, sending an electrical signal to the controlling system.

Conclusion

The E3G-ML79-US optical sensor series is a highly sensitive and versatile sensor, capable of meeting the demands of industrial applications. With its wide range of sensing capabilities, it can accurately monitor and measure distances and objects in motion, as well as serve as a presence detection system. It is a reliable and cost-effective solution for industrial monitoring systems.
