1. Long detection distance

If the detection distance of 10 m or more is retained in the through-beam type, it is possible to achieve detection that is not possible with other detection methods (magnetic, ultrasonic, etc.).

2. There are few restrictions on the detected objects

Since the detection principle is based on the detection of light shading and reflection caused by objects, unlike proximity sensors, which limit the detection of objects to metal materials, photoelectric sensing can detect almost all objects such as glass, plastic, wood, and liquids.

3. Short response time

Since the light itself is high-speed, and the circuitry of the sensor is composed of electronic parts, the response time is very short, excluding mechanical operating time.

4. High resolution

High resolution can be achieved by concentrating the projection beam at a small spot through advanced design techniques or by constructing a special light-receiving optical system. It is also possible to detect small objects and detect positions with high accuracy.

5. Non-contact detection can be realized

Detection can be achieved without mechanical contact with the detected object, so there is no damage to the detected object or the sensor. As a result, the sensor can be used for a long time.

6. Color discrimination can be realized

The reflectivity and absorption of the light formed by detecting an object vary depending on the wavelength of the light being emitted and the color combination of the detected object. With this property, the color of the object can be detected.

7. Easy to adjust

In the type of projected visible light, the projected beam is visible to the eye, and the photoelectric guiding system can adjust the position of the detected object.
