P+F Pepperl+Fuchs encoder, it's time to witness the miracle

Pepperl+Fuchs encoder detects the displacement and speed of the movable part, and then outputs it as a digital signal. It is suitable and applied to the computer control of mechanical devices. There are many types of encoders, which can be classified according to their operating principles or measurement objects. According to the operating principle, it is divided into optical type, magnetic type, brush type, electromagnetic induction type and so on.

The optical and magnetic types of Pepperl+Fuchs encoders are the most commonly used.

According to the detection object, it is divided into linear encoder for measuring linear displacement and rotary encoder for measuring angular displacement. It can be divided into incremental type that outputs relative displacement and absolute type that outputs absolute displacement. Rotary encoders are characterized by small size, light weight, multiple varieties, complete functions, high frequency response, high resolution, small torque, low energy consumption, stable performance, reliable and long service life. The absolute encoder is called the multi-turn absolute encoder, it is also determined by the mechanical position of the code, 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. A friend said that when using it, it was found that the encoder sometimes appeared abnormal. , Check how the encoder's insulation to ground, and magnetic field interference, etc. Check whether there is vibration or not, whether the installation is inconsistent. In addition, check whether there is interference on the common power supply and wiring. The encoder is a magnetic core product, so you must pay attention to the use environment!
