Pepperl+Fuchs Code-writer in the industrial control industry of encoders

P+F Pepperl+Fuchs encoders are powerful, but they are constantly striving for perfection. Two branches of Pepperl+Fuchs encoder: Pepperl+Fuchs encoder absolute value type, Pepperl+Fuchs encoder incremental type. Pepperl+Fuchs encoders can be used to measure angle, position, speed and angular velocity in the field of industrial automation. By using racks, measuring wheels and constant force opening meters, we can measure linear motion positions.

The distance between the front face of the photoelectric sensor and the reflector is kept within the specified range; the photoelectric sensor must be installed in a place where there is no direct irradiation of strong light, because the infrared light in the strong light will affect the normal operation of the receiving tube; the infrared emitting tube of the photoelectric sensor The linearity between the luminous intensity and the current is the best when the current is between 2 and 10 mA, so the current value generally does not exceed this range. This should be considered in the structural design, and try to avoid unfavorable factors such as external light interference. P+F Pepperl+Fuchs photoelectric switch objects are not limited to metals, all objects that can reflect light can be detected. The common photoelectric switch smoke alarm in the security system is often used in the industry to count the number of movements of the mechanical arm. Reflective photoelectric sensor The parameter selection method of the best working condition of the photoelectric sensor in the specific working environment: select the model of the photoelectric sensor according to the actual detection distance. The photoelectric sensor counts according to the intensity of the reflected infrared light, so the most critical point in selecting the working point, installation and use is that the receiving tube must work in the cut-off zone and the saturation zone; secondly, the front face of the photoelectric sensor is in use with The surface of the workpiece or object to be inspected must be parallel.
