P+F Pepperl+Fuchs Encoder Rotating Technology Era Witnesses the Miracle of Development

The P+F 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.

P+F Pepperl+Fuchs coded encoders can be classified according to the output characteristics and can be classified into the following categories: 1. Photoelectric: It is composed of a main ruler and a sub ruler engraved with a grating. 2. Magnetic moving type: Consists of a magnetic head and a long rod plated with a magnetic layer. 3. Electrostatic capacitance type: It is composed of the main ruler of the receiving electrode, the secondary ruler of the transmitting electrode and the quality measuring electrode. 4. Electromagnetic type: consists of an inductive slider coil and a metal substrate with a scale. 5. Brush type. Photoelectric encoders are classified according to their measurement objects and can be divided into: 1. Photoelectric length encoders (grating scales, optical scales), 2. Photoelectric circular encoders: angles are used as measurement objects, but they are also often used for precision linear length In measurement occasions. The optical and magnetic 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.
