Optical Sensors - Photoelectric, Industrial

Optical sensors are gadgets that use optical recognition to detect, measure, or perceive physical or chemical changes in the environment. This type of sensor works by detecting changes in light or radiation levels, or detecting reflections, shadows or specular reflections in the environment. They are commonly used to measure distances, angles, and displacement, and can be found in many different industries, including consumer electronics, medical industries, automotive and industrial applications.

The 70156-4028 optical sensor is an industrial-grade photoelectric sensor designed to detect objects or surfaces in a wide range of applications. It is composed of an emitter and a receiver which are each equipped with an array of photodecoder circuits. When an object passes through the light beam created by the emitter, the photodecoder circuits accurately detect its presence. The array of photodecoders also enables the sensor to distinguish various levels of brightness or absence of any object in the environment.

When it comes to its operation, the 70156-4028 is powered by a small 3V DC battery and is capable of detecting anything in its sensing range through an LED light beam. This LED light beam can be modulated at frequencies up to 200 kHz in order to enable varying sensing distances. The emitter features a light output power of 28 mW and a sensing angle of 30 degrees. It is also equipped with LED status indicator for monitoring the status of each sensing photocell. The receiver features a receiving sensibility that can detect objects at distances up to 80 mm. The 70156-4028 can also work as a two-wire system, providing small pulse output when an object is detected.

Due to its long range sensing capability and two-wire input/output configuration, the 70156-4028 is suitable for a variety of industrial applications, including object detection, material handling, and counting. It is also used in medical equipment to control motion and for security purposes. Other applications include robotic navigation, traffic control, and machine vision systems.

In conclusion, the 70156-4028 is an excellent optical sensor for industrial applications. It is a reliable and robust sensor capable of withstanding a wide variety of environmental conditions. The two-wire configuration and the LED light beam make it easy to integrate with existing systems and enable efficient detection of objects at long distances. This, together with its outstanding performance, makes it an ideal choice for a variety of industrial applications.
