Introduction

The 70156-4352 (hereafter referred to as the element) is a versatile and widely-used Photoelectric/Industrial optical sensor, and has become an indispensable component for many industrial applications. This article will discuss the applications of the element, and more importantly, the working principle behind it.

Applications

Photoelectric sensors are used in a variety of industrial, commercial, and scientific applications, such as machine vision and robotics, automated production lines, material handling and sorting systems, quality control, and safety systems. Industrial sensors are employed in food processing, automotive assembly, fire and gas detection, security and surveillance, machine control, and other fields. Common applications include proximity sensing, object detection, motion and distance measurement, robotics, and automation.The 70156-4352 is especially well-suited for these applications due to its reliable output and robust construction. It is designed to detect small objects, and its two-wire connection allows for simple wiring and low power consumption. It is capable of detecting objects from 0.2mm to 15mm away from its surface, which makes it ideal for position detection and material handling applications. Additionally, the element is resistant to dust and moisture, and its robust construction ensures a long service life.

Working Principle

The 70156-4352 is an optical element which utilizes a light-emitting diode (LED) to illuminate the target area, and a phototransistor to detect the reflection of the light. The light beam emitted by the LED is focused by a lens onto the targeted area, and the light that is reflected is then detected by the phototransistor. The output of the phototransistor is then amplified and converted into a proportional voltage.The operation of the element is based on the “dark” and “light” effect. This means that when the phototransistor detects a reflection of light, a change in output voltage is detected. When the light beam is obstructed, the output voltage is reduced. This dual behavior allows the element to detect presence and absence of objects in the target area, as well as their proximity.

Conclusion

In conclusion, the 70156-4352 is a reliable and widely-used industrial Photoelectric/Industrial optical sensor, and its versatile design makes it ideally suited for a variety of applications. Its operation is based on the “dark” and “light” effect, which utilizes a LED and a phototransistor to detect the reflection of light. The element is designed to detect objects from 0.2mm to 15mm away from its surface, and its robust construction ensures a long service life.
