Optical sensors are devices that detect specific portions of the electromagnetic spectrum. They can be divided further into four sub-categories, namely photoelectric, industrial, passive, and active optical sensors. In this article, we will be discussing the application field and working principle of the 70156-2019 optical sensor, which is classified as an industrial photoelectric optical sensor.

Application Fields of the 70156-2019

The 70156-2019 optical sensor is often used in industrial automation settings. Manufacturers rely on such sensors for monitoring machine performance in factories, as they can detect changes in the light generated by mechanical processes. They are also often used in robotic arms, due to their ability to detect the movement and position of objects accurately. Furthermore, they are utilized in measuring distance for object avoidance, and have found applications in medical technologies.

Working Principle of the 70156-2019

The 70156-2019 optical sensor is based on the principle of photometry, making use of a light-sensitive photodiode to measure visible and infrared radiation. In order for the sensor to detect and measure the amount of light it receives, it makes use of a conditioning amplifier, which amplifies the weak electrical signal generated by the photodiode. This amplified signal is then sent to a microprocessor, which processes the information and transmits the readings to a connected device, such as a computer or a controller.

In industrial applications, the 70156-2019 is usually installed directly to a robotic arm and acts as its vision or distance measurement system. The sensor can measure the distance from the arm to an object, by obtaining the object\'s attributes through light reflection. These objects can be items of varying sizes, shapes, and colors. Additionally, the sensor can even measure the distance of an object without the use of a robotic arm.

Conclusion

The 70156-2019 industrial photoelectric optical sensor is a reliable and versatile tool for various applications. It is mainly used for measuring distances, determining the movement and position of objects, and providing feedback in industrial automation settings. By utilizing photometry and a photodiode, the sensor can accurately detect and measure different levels of light. The amplified signal received from the photodiode is then sent to a microprocessor which processes the data and transmits it to the connected device. Furthermore, the 70156-2019 can measure distance even without the use of a robotic arm.
