Recommended reading by technical consultants of okplazas.com Differences in functions of Pepperl+Fuchs encoders

In the field of automation, P+F Pepperl+Fuchs encoders are used to detect angles, positions, speeds and accelerations. Rely on shafts, gears, measuring wheels, etc. The encoder also installs the actual mechanical parameter values into signals, which can be processed by counters, tachometers, PLCs and industrial PCs. Encoders have different differences according to their functional principle and mechanical form and installation system. If classified according to the functional principle, it can be divided into: incremental rotary encoder and absolute rotary encoder.

Each position determined by the mechanical position of the absolute encoder is unique. It does not need to be memorized, does not need to find a reference point, and does not need to be counted all the time. When it needs to know the position, when to read its position. The anti-interference characteristics and data of the encoder are reliable. The encoder manufacturer uses the principle of clock gear mechanism. When the center code disc rotates, another set of code discs are driven by gears, and the number of turns is encoded on the basis of the single-turn encoding to expand the measuring range of the encoder. The absolute encoder is called a multi-turn absolute encoder, which is also determined by the mechanical position. Each position code is unique and does not need to be memorized. The commonly used incremental encoder is an absolute encoder if there are strict requirements on the position and zero position. The servo system should be analyzed in detail to see the application. Commonly used incremental encoders for speed measurement can be cumulatively measured infinitely; absolute encoders for position measurement are unique in position, depending on the purpose and requirements to be achieved.
