Optical sensors, also known as photoelectric sensors, are devices which use light to detect the presence or absence of an object, the change in an object\'s position, or the change in its surface characteristics. Industrial optical sensors are used in a wide range of applications, from liquid level detection to fiber-optic communication systems. In this article, we\'ll look at the application field and working principle of model 70156-2766, an industrial optical sensor.

Applications

Industrial optical sensors have a wide range of uses, and model 70156-2766 is designed to be used in industrial control systems. It can be used to detect the presence and absence of objects, measure distances, monitor the position of rotating parts in machinery, detect liquid levels, and observe surface characteristics. This model is particularly suitable for liquid level monitoring, as it is programmed to detect changes in light refraction, which occurs when liquids with different densities are placed in its field of view.

In addition to the above, model 70156-2766 can be used in a variety of automated material handling and sorting systems, as it can detect objects positioned on a conveyor belt. This makes it ideal for applications such as package sorting in warehouses and mailrooms, and for controlling the flow of materials in manufacturing processes.

Working Principle

Model 70156-2766 makes use of a type of infrared light known as Infrared-LED (light emitting diodes). Infrared-LEDs are designed to produce light waves in the near infrared spectrum, making them ideal for industrial applications where the distance being measured needs to be accurate and the object being measured needs to be positioned within a certain range. The light waves produced by the Infrared-LED are picked up by a photodiode, which converts the light waves into an electrical current. This current is then used to power the sensor circuitry, which sends a signal to the controller indicating the presence or absence of an object.

When a user starts the system, the Infrared-LEDs begin to draw power from the photodiode. Depending on the distance of the object being measured, the light waves will be absorbed or reflected in different amounts. The photodiode will convert this into an electrical current, and the current will have a different intensity depending on the distance of the object. A signal is then sent to the controller, which is used to trigger certain commands.

In addition to the above, model 70156-2766 is also programmed to detect changes in light refraction when liquids with different densities are in its field of view. This is achieved by using a technique known as \'triangulation\', in which the Infrared-LEDs and photodiode are configured to detect any changes in the intensity of the light they are receiving.

In summary, model 70156-2766 is an industrial optical sensor designed for use in control systems. It is programmed to detect the presence or absence of objects, measure distances, monitor the position of rotating parts in machinery, detect liquid levels, observe surface characteristics, and detect changes in light refraction. The working principle of this model is based on Infrared-LEDs and a photodiode, which convert light waves into an electrical current. This current is used to power the sensor circuitry and send a signal to the controller indicating the presence or absence of an object.
