Optical sensors are a type of sensor that capture information about physical properties of objects like color, shape, size, and texture; this information is then used to determine the characteristics of the object. The most commonly used optical sensor is the photoelectric type; these are used to detect the amount of light within a certain area, which is then used to measure distances or detect the presence of objects in the vicinity. One particular type of photoelectric sensor is the 70156-2868 series of devices, which are primarily used in industrial and commercial applications. This article will discuss the 70156-2868 series of sensors and its applications and working principles.

The 70156-2868 optical sensors can be used to detect objects in both dark and bright environments. The device uses 4 Semiconductor Photomultiplier Tubes (PMT) to detect the light, and these tubes are sensitive to a wide range of spectra from near-infrared (NIR) to ultraviolet (UV). The use of PMT allows for reliable sensing in both dark and bright environments; this is because the PMT can detect even faint levels of light in the dark and the presence of objects in bright environments. In addition, the device is also capable of detecting changes in the amount of light, allowing for more precise measurements.

The 70156-2868 series of sensors can be used in a variety of applications, such as detecting the presence of objects in industrial and commercial processes, or detecting the proximity of hazardous materials in areas with limited visibility. It can also be used in the automation of robotic tasks or to identify objects on manufacturing lines. The device is also capable of detecting changes in wavelength and intensity of light sources, allowing for more accurate measurements. Additionally, the sensor also has a built-in signal processor, which ensures that the signals received by the PMT are properly filtered.

The working principle of the 70156-2868 series of sensors is quite simple. When the sensors detect a significant level of light, the detected signal is then filtered by the processor and the output signal is then amplified. The amplified signal is then sent to a digital output port, which can be used to control other devices in the area. The device can also be programmed to address certain features, such as the detection of certain colors or wavelengths.

In conclusion, the 70156-2868 series of optical sensors is an important device for industrial applications due to its ability to detect objects in both dark and bright environments. The sensor is also capable of detecting changes in wavelength and intensity of light sources, allowing for more accurate measurements. Additionally, the built-in signal processor ensures that the signals received by the PMT are properly filtered. With its wide range of applications, the 70156-2868 series of sensors is a useful device for many industries.
