Information

The three common types of China photoelectric beam sensors are beam type, retro-reflection type, and diffuse reflection type.
Through-beam type: This type of China photoelectric beam sensor is used with a light emitter and a light receiver. The detection distance is long, it must be installed on both sides and both need a power supply. This type of China photoelectric beam sensor can detect tiny objects after installing a slit (later, there is no strict requirement for the color of the object. It requires optical axis alignment, and the cost is high.China photoelectric beam sensorRetro-reflective type: This type of China photoelectric beam sensor must be used in conjunction with a reflector. The detection distance is shorter than that of the opposite-beam type, so it must be installed on both sides. It is recommended to use it to detect transparent objects. If the detection object is a mirror object with strong reflection, it is recommended to use a retro-reflective photoelectric beam sensor with corresponding functions. Optical axis alignment is required, and the cost is lower than the through-beam type.
Diffuse reflection type: This type of China photoelectric beam sensor can be used alone and can be installed on one side. And the diffuse reflection photoelectric beam sensor has requirements for the detection object, the detection object should be large, the color of the object should be light, the detection surface should be flat and the object should be opaque. However, this type of China photoelectric beam sensor has a short detection distance, does not need to be aligned with the optical axis, and has a low cost.
