Optical sensors, or photoelectric sensors, are devices that use electronic devices to measure and detect transmission of light energy. Industrial optical sensors, such as the model 70156-1555, are employed in various industrial applications such as automation, industrial machinery, manufacturing processes, and robotics. This article will discuss the application field and working principle of the optical sensor model 70156-1555.

Classification of Optical Sensors

Optical sensors can be broadly classified into three types according to their working principles: active, passive, and hybrid. Active optical sensors have an optical source that emits light, such as a laser or LED, that is then detected by an optically sensitive element, such as photodiode or phototransistor. Passive optical sensors use reflected ambient light instead of an active light source, and hybrid optical sensors employ both technologies. In the case of the model 70156-1555, the sensor is classified as a passive optical sensor.

Application Field of Model 70156-1555

The model 70156-1555 is a general-purpose infrared optical sensor designed for industrial applications. It is used mainly for detecting obstacles when operating machinery or robots, and it is also found in industrial automation, movement control, and safety systems. The sensor operates on the detection of changes in infrared radiation, which is one form of electromagnetic radiation that lies in the invisible spectrum. When infrared radiation is absorbed or reflected, the model 70156-1555 detects it and triggers the appropriate response.

Working Principle of Model 70156-1555

The model 70156-1555 is a passive infrared (PIR) optical sensor that detects changes in the infrared light radiation. It consists of an infrared-sensitive receiver and an infrared-sensitive transmitter. The system is typically mounted on a wall or pole such that the transmitter is pointed towards the area to be monitored. When an object passes through the infrared beam, the sensor detects a change in the infrared radiation and sends a signal to activate the response. The distance of the object and its size and shape can also be measured by the model 70156-1555.

The model 70156-1555 is also equipped with a logic circuit, which is used to process the signals from the environment and generate the appropriate output response. The logic circuit includes a threshold setting, which is used to set the sensitivity of the sensor. The logic circuit can also be used to regulate the response time and range of the sensor, depending on the user’s requirements.

Conclusion

The model 70156-1555 is a general-purpose optical sensor for industrial applications that operates on the detection of changes in infrared (IR) radiation. It is a passive optical sensor that consists of an infrared-sensitive receiver and transmitter. The receiver transmits signals to the logic circuit, which processes the signals and triggers the relevant response. The logic circuit also allows for customizing the threshold setting, response time, and range of the model 70156-1555.
