The uniqueness of each position of the P+F Pepperl+Fuchs encoder is determined by the mechanical position. It does not need to be counted all the time. Whenever the position needs to be known, it is read when. In this way, the anti-interference characteristics of the encoder and the reliability of the data are greatly improved. It is enough to use a certain intermediate position as the starting point, which greatly simplifies the difficulty of installation and debugging. Multi-turn absolute encoders have obvious advantages in length positioning, and they have been increasingly used in industrial control positioning.

The electrical signal of P+F Pepperl+Fuchs encoder is processed by CNC, programmable logic controller PLC, control system and so on. These sensors are mainly used in the following areas: machine tools, material processing, motor feedback systems, and measurement and control equipment. The conversion of angular displacement in the ELTRA encoder adopts the photoelectric scanning principle. The reading system is based on the rotation of the radial indexing plate. The indexing is generally divided into incremental type and absolute type by alternating light-transmitting window encoders. They have the biggest difference: in the case of incremental encoders, the position It is determined by the number of pulses counted from the zero mark, and the position of the absolute encoder is determined by the reading of the output code. In a circle, the reading of the output code of each position is unique; therefore, when the power is disconnected, the absolute encoder is not separated from the actual position. If the power is turned on again, the position reading is still current and valid; unlike the incremental encoder, the zero mark must be searched for. And opaque windows.
