Optical Sensors - Photoelectric, Industrial: 70156-2672 Application Field and Working Principle

Optical sensors are used to detect physical changes in the environment by converting light into electric signals. They are commonly used in industrial, military, medical, and consumer applications. The 70156-2672 Photoelectric Industrial Sensor is the first generation optical sensor developed by Sony for use in industrial applications. This sensor is designed to be used in harsh environments where traditional photoelectric sensing solutions may not be suitable.

The 70156-2672 Photoelectric Industrial Sensor is a combination of a light-sensitive element (a diode) and a transducer (a device that converts energy between two different forms). The light-sensitive element, known as the active element, is a reverse-biased semiconductor diode that emits a current when light is incident upon it. The transducer then converts the current into a voltage output, which is used to detect the change in the environment.

The 70156-2672 Photoelectric Industrial Sensor has two operating modes, direct sensing and indirect sensing. In direct sensing, the light-sensitive element (diode) is directly exposed to ambient light. The voltage generated by the diode is directly proportional to the amount of light incident upon it. This output can be used to measure the amount of light present in an environment, as well as detecting small changes in that environment.

In indirect sensing, the light-sensitive element is not directly exposed to ambient light, but rather is behind an optical filter that passes a certain portion of the light. The output voltage is then measured over a range of different filter weights, allowing for more accurate detection of changes in the environment.

The 70156-2672 Photoelectric Industrial Sensor is designed to respond quickly to changes in the environment, which makes it suitable for use in harsh environments. Its small footprint also makes it ideal for use in tight spaces. The sensor can be used in a wide range of industries, from automotive to security to robotics.

In conclusion, the 70156-2672 Photoelectric Industrial Sensor is a reliable and versatile sensor designed to deliver high performance in harsh environments. Its unique combination of direct and indirect sensing capabilities allows for accurate detection of changes in the environment, making it ideal for a wide variety of industrial applications.
