Optical sensors play a major role in the realm of industrial automation. Specifically, the 70156-3888 model optical sensor has seen great success when deployed in various Automation and Machine Vision applications. This article will discuss the application fields and working principles of the 70156-3888.

Application Fields

The 70156-3888 is a high-precision photoelectric sensor with several different specialty application fields. For instance, the 70156-3888 is often used in the automotive industry for gear shift position detection. This is due to the sensor’s high repeatability, accuracy, and response time.The sensor is also an ideal choice for vision applications due to its high resolution and low f-number. According to product literature, the sensor can detect object positions within 0.01mm accuracy and has a maximum resolution of 1,920 pixels.Additionally, the 70156-3888 is suitable for other general automation applications such as level detection, defect inspection, and material sorting. It is capable of operating under a wide range of environmental conditions, from -20°C to +80°C.

Working Principle

The 70156-3888 operates using a light-dependent resistor (LDR) technique. An LDR is a type of resistor whose resistance changes depending on the intensity of the light that it absorbs. In the case of the 70156-3888, the LDR is positioned in front of the camera lens. When light is detected by the LDR, its resistance changes, which in turn affects the voltage output of the sensor.The voltage output is then read by an analog-to-digital converter (ADC). The ADC converts the voltage into a digital signal, which can then be used by the microcontroller to control various outputs. As it processes the signal, the microcontroller also performs several other functions such as image stabilization, noise reduction, and image resolution adjusting.

Conclusion

In conclusion, the 70156-3888 is a versatile and reliable model of optical sensor with many applications in the worlds of Automation and Machine Vision. Its high-precision LDR technique allows for accurate and sensitive detection of objects and materials, and its robust design ensures reliable operation in a range of environments. As such, the 70156-3888 has earned a well-deserved reputation for industrial excellence.
