Optical Sensors - Photoelectric, Industrial

Optical sensors are devices used to detect the presence of objects, or measure the characteristics of the environment, based on the light they reflect. They use either infrared (IR) or visible light to detect objects, people, or environmental conditions. Examples of optical sensors include photoelectric sensors, infrared sensors, and proximity sensors.The 70156-2851 is an industrial photoelectric sensor, designed to detect the presence of objects in a wide range of industrial applications. The sensor operates by detecting changes in the reflected light from the target object. When the target object moves into the sensor\'s field of view, the sensor is triggered and an output signal is generated.The 70156-2851 is designed for use in harsh industrial environments, such as in factories, loading docks, or warehouses. It is rated to IP67 protection level. This means that it can withstand dust, dirt, water, and low temperatures, making it ideal for outdoor applications as well.The sensor has a built-in amplifier, so the output signal is strong and reliable. It also has a wide field of view, allowing it to detect objects that are up to 1 meter away. The sensor is also equipped with laser sensing technology, which enables it to detect even small objects, such as a pin or a coin.The 70156-2851 sensor has two detection modes: background suppression and foreground suppression. Background suppression is used when the target object is large and bright. In this mode, the sensor looks for changes in the background. When the target object enters the field of view, the sensor passes a high signal to the controller. On the other hand, foreground suppression is used when the target object is small and dim. In this mode, the sensor looks for an increase in the light level from the target object. When the target object enters the field of view, the sensor passes a low signal to the controller.The 70156-2851 is a versatile photoelectric sensor, capable of detecting the presence of objects in a range of industrial applications. Its laser sensing technology, wide field of view, and IP67 protection level make it ideal for outdoor environments. It also has two detection modes, making it suitable for detecting both large and small objects.
