Brand is not as good as quality, speak with advantage okplazas.com recommends Pepperl+Fuchs encoder

The 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. P+F Pepperl+Fuchs encoders are classified into optical type, magnetic type, brush type, electromagnetic induction type, etc. according to the operating principle. Among them, optical and magnetic 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.

Encoders can be classified according to output characteristics and can be classified as follows: 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. Since the linear and rotational movement of the machine is often driven by the rotation of the motor and decelerated and converted, circular encoders are more common than length encoders. The circular encoder is also called the shaft encoder. It counts the rotation angle of the shaft and multiplies it with the screw pitch of the machine, so that the length of the stroke can be calculated.
