Encoders are commonly used in the machine tool, textile and other industries, and are divided into two types: absolute value and incremental value. The incremental P+F Pepperl+Fuchs encoder has zero cumulative error and poor anti-interference. The receiving device needs to be memorized when it is powered off when it is shut down, and the change or reference position should be changed when it is turned on. These problems can be solved by using an absolute encoder. General applications of incremental encoders: measuring speed, measuring direction of rotation, measuring moving angle and distance (relative).

Pepperl+Fuchs encoder

P+F Pepperl+Fuchs rotary encoder is a device used to measure speed. It is divided into single-channel output and dual-channel output. Technical parameters mainly include the number of pulses per revolution (dozens to thousands of them), and power supply voltage. Single output means that the output of the rotary encoder is a set of pulses, while the dual output rotary encoder outputs two sets of pulses with a phase difference of 90 degrees. The two sets of pulses can not only measure the speed, but also determine the direction of rotation. The difference between an incremental encoder and an absolute encoder is that the zero reference position of the encoder can be obtained through the zero pulse. The materials of the encoder code disc are glass, metal, plastic. The glass code disc is deposited on the glass with very thin lines, which has good thermal stability and high precision. The metal code disc is directly engraved with through and impassable lines and is not fragile. However, because metal has a certain thickness, the accuracy is limited, and its thermal stability is an order of magnitude worse than that of glass. Plastic code discs are economical, and their cost is low, but accuracy, thermal stability, and life are worse. . The general application of Pepperl+Fuchs encoders is that the encoders are mainly used in CNC machine tools and mechanical accessories, robots, automatic assembly machines, automatic production lines, elevators, textile machinery, sewing machinery, machinery (fixed length), machinery (synchronization), woodworking machinery , Plastic machinery, rubber and plastic machinery, drawing instruments, goniometers, convalescent radars, etc.
