(1) Long detection distance
If the detection distance of more than 10m is reserved in the shooting mode, other detection methods (magnetism, ultrasound, etc.) can not be long-distance detection.
(2) Less restrictions on detection objects
Because of the detection principle of shading and reflection caused by the detection object, it can detect almost all objects, such as glass, plastic, wood, liquid and so on, unlike proximity sensors, which limit the detection object to metal.
(3) Short response time
Light itself is high-speed, and the circuit of the sensor is composed of electronic parts, so it does not include mechanical working time, and the response time is very short.
High resolution can be achieved by focusing the projected beam on a small spot through advanced design techniques or by forming a special optical system for receiving light. It can also be used for the detection of micro-objects and high-precision position detection.
Non-contact detection can be realized
It can detect objects without mechanical contact, so it will not cause damage to the detected objects and sensors. Therefore, the sensor can be used for a long time.
Color discrimination can be realized
The reflectivity and absorptivity of the light formed by the object are different according to the www.dianLiwuzi.com.cnwww.btwujin.cnwww.bjsrxhsart.cnwww.huafuly.cnwavelength of the projected light and the color combination of the detected object. Using this property, the color of the detected object can be detected.www.huizhuanyao5.com.cnwww.gzdebon.com.cn
Easy to adjust
In the type of projected visible light, the projected beam is visible to the eyes, which is convenient for adjusting the position of the detected object.
