70156-1931

Optical sensors are widely used in industry and other automated systems. Perhaps one of the most commonly used of these sensors is the 70156-1931. This sensor is a photoelectric one, meaning it uses light to measure changes in its environment. Through this article, we\'ll explore the application fields and the working principle of this sensor type in greater detail.

Application fields

The 70156-1931 series of photoreflectors are mainly used in the industrial sector. They have high applicability in machine processes, for example in metal fabrication, sheet metal processing, wood processing, plastics, and many other industries. Photoreflectors are also widely used in the control and automation of production. With its compact size and strong construction, it is suitable for most demanding industrial environments.

The 70156-1931 sensor is especially suited for use in environments with high vibration and shock. Its anti-vibration and shock resistance feature make it ideal for use in confined spaces. Additionally, its IP67 rating makes it suitable for use in dusty and wet environments.

Working Principle

The 70156-1931 series of sensors operates based on the photoreflective principle. This means that it uses light from a light source to measure the difference between its environment and the desired object or event. The light intensity that affects the sensor varies depending on the environment and the surrounding materials.

When the desired object or event is detected, the light that reaches the sensor is attenuated, and this attenuation is detected by the device. The result is that the device is able to provide an input when the desired object or event occurs, thereby allowing for automated control of the process.

The specific type of light used in this sensor series is modulated infrared light of a specific frequency, which helps to ensure a good strength of signal. The light intensity is adjustable, which allows for a wide range of application scenarios.

The 70156-1931 series of sensors requires a minimum of power to run. This makes it an ideal choice for battery-operated or energy-saving systems.

Conclusion

The 70156-1931 is a type of photoreflective industrial sensor. It has a wide range of applications in industrial environments, especially those with high vibration and shock. Its working principle involves the use of modulated infrared light of a specific frequency to measure the difference between the sensor environment and the desired object or event. Additionally, the sensor itself requires minimal power to operate, making it ideal for battery-operated or energy-saving systems.
