Features of radio frequency sensors

　　has the following characteristics in industrial production applications:

　　1. Long detection distance

　　If the detection distance of 10m or more is reserved in the through-beam type, it can realize that other detection methods (magnetic, ultrasonic, etc.) cannot detect long distances.

　　2, there are few restrictions on detecting objects

　　As the detection principle is based on the shading and reflection caused by the detection object, unlike the radio frequency sensor, which limits the detection object to metal, it can detect almost all objects such as glass, plastic, wood, and liquid.

　　3, short response time

　　The light itself is high-speed, and the circuit of the sensor is composed of electronic parts, so mechanical working time is not included, and the response time is very short.

　　4, high resolution

　　High-resolution design technology can be used to concentrate the projected light beam on a small spot, or to form a special light-receiving optical system to achieve high resolution. It can also detect small objects and high-precision position detection.

　　5, non-contact detection can be realized

　　The detection can be achieved without mechanically touching the detection object, so it will not cause damage to the detection object and the sensor. Therefore, the sensor can be used for a long time.

　　6. Color discrimination can be realized

　　The reflectance and absorptivity of the light formed by the detection object differ according to the combination of the wavelength of the light projected and the color of the detection object. Using this property, the color of the detected object can be detected.

　　7, easy to adjust

　　In the type of projected visible light, the projected light beam is visible to the eyes, which is convenient for adjusting the position of the detection object.
