P+F Pepperl+Fuchs Encoder Rotating Encoding New Technology

The P+F Pepperl+Fuchs encoder is a rotary sensor that converts the rotation displacement into a series of digital pulse signals. These pulses can be used to control the angular displacement. If the encoder is combined with a gear bar or a spiral screw, it can also be used Measure linear displacement.

P+F Pepperl+Fuchs encoders are generally divided into incremental and absolute encoders, and they have the biggest difference: in the case of incremental encoders, the position is determined by the number of pulses calculated from the zero mark, and The position of the absolute encoder is determined by the reading of the output code. Incremental type is to directly use the principle of photoelectric conversion to output three sets of square wave pulses, and use pulses per revolution for reference point positioning. It has the advantages of simple principle structure, average mechanical life of more than tens of thousands of hours, strong anti-interference ability, high reliability, and suitable for long-distance transmission. Different types of rotary encoders have different phase numbers of output pulses. The encoder is small in size, precise, and can have high resolution, no contact and no wear; the same type can detect angular displacement, but also can detect linear displacement with the help of a mechanical conversion device; multi-turn photoelectric absolute encoders can detect quite long ranges的linear displacement. The encoder does not need to memorize, find a reference position, or keep counting. The mechanical input can be converted into electrical signals, which can be processed by counters, tachometers, programmable logic controllers and industrial computers.
