Optical Sensors - Photoelectric, Industrial

Modern industry makes inventive use of optics with the development of optical sensors. Different types of sensors are used to measure different physical phenomena. Photoelectric sensors and industrial sensors are two types of optical sensors commonly used in industrial applications. This article will focus on the application field and working principle of the 70156-2259 sensor series.

Application Field of the 70156-2259 Sensor Series

The 70156-2259 series is a range of photoelectric sensors featuring a robust design and long range detection. The sensor adopts a cylindrical shape with two mounting points. Thanks to the optical lens, the sensing distance can be adjusted according to the specific requirements of the application. The 70156-2259 series sensors are suitable for use in either narrow or wide field applications where a high level of precision is required. They offer a fast response and high accuracy, even in hostile industrial environments. The series is suitable for a wide range of industrial applications, such as level sensing, door sensing, product presence checking, color detection, and product alignment.

Working Principle of the 70156-2259 Sensor Series

The working principle of the 70156-2259 series is based on the light-to-voltage conversion principle. The design includes an infrared LED light source, a lens, and a receiver. When the sensor is triggered, the light source emits an infrared light beam, which is reflected off the object and detected by the receiver. The receiver converts the optical signal to an electrical signal, and the signal is further processed to calculate the distance between the sensor and the object. The signal is then used to trigger control functions or activate output signals. The range and accuracy of the detection depend on the lens and the sensitivity of the receiver.

Conclusion

The 70156-2259 series is a versatile range of photoelectric sensors that offer long range detection and fast response. The sensors are suitable for a wide range of industrial applications, such as level sensing, door sensing, product detection, color detection, and product alignment. The working principle of the series is based on the light-to-voltage conversion principle, where the infrared light beam from the sensor is reflected off the object and detected by the receiver. The range and accuracy of the detection depend on the lens and the sensitivity of the receiver.
