The 70156-3991 Optical Sensor is a type of photoelectric sensor that is widely used in industrial applications. This sensor is composed of an infrared or visible light source, an optical interruption, a photosensitive element and a control circuit. The sensing element consists of a receiver and a phototransistor, which can detect changes in the light level caused by the presence or absence of an object. The phototransistor then triggers the control circuit to activate the photoelectric sensor.

The 70156-3991 Optical Sensor is designed to detect objects up to 10 cm away. The detection range can be further adjusted by changing the number of photoelectric elements or the photosensitivities of the elements. When in use, the sensor can detect changes in the amount of light caused by the interruption of the light beam. This method of detection is reliable and can detect objects accurately and quickly.

The 70156-3991 Optical Sensor has many industrial applications. It is often used to detect objects in industrial automation systems, conveyor systems, robotics, and various other automation equipment. It is also used to detect objects for safety applications such as switches and door sensors. In addition, the sensor can be used for color detection applications as well.

The main principle behind the 70156-3991 Optical Sensor is based on the concept of light reflection and absorption. When an object is present in the sensor’s field of view, it will absorb and reflect some of the light that is being emitted by the sensor. The amount of absorption and reflection varies depending on the material of the object and its color. The control circuit in the sensor can detect these changes in light levels and converts them into electrical pulses. The pulses are then used by the control system to indicate the presence of an object.

In conclusion, the 70156-3991 Optical Sensor is an important tool for industrial applications. It can detect objects quickly and accurately, provide reliable safety features, and can be used for color detection. Its main working principle is based on the concept of light reflection and absorption. This sensor is a reliable and cost-effective tool for automation and safety applications.
