P+F Pepperl+Fuchs Encoder New Power of Coding Technology

It is estimated that most of the industrial control friends are familiar with the term P+F Pepperl+Fuchs encoder. Encoders are widely used, small in size, precise, with 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 encoder It can detect the linear displacement of a fairly long range. The encoder does not need to memorize, find a reference position, or keep counting.

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. There are two types: incremental and absolute. They have the biggest difference: In the case of an incremental encoder, the position is determined by the number of pulses counted from the zero mark, while the position of an 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. Encoders can convert mechanical inputs into electrical signals, which can be processed by counters, tachometers, programmable logic controllers, and industrial computers.
