The encoder is a subset of the sensor family, because it converts the mechanical movement (rotational or linear) into an electrical signal and sends the feedback of the movement parameters (speed, distance, direction, etc.) to the control unit such as the PLC. After checking the feedback, the PLC Sends the necessary commands to the operators. Considering the high importance of encoders in devices and industries, it is suggested to always use the best and most expensive ones, because their failure can cause many losses to the system. The main function of the encoder is to get feedback from the movement and control the position, direction, distance, angle of rotation and movement speed.

Encoder) buying guide:
If you are looking to buy the right rotary encoder, it is necessary to determine the following parameters to choose the right encoder:
body size**
shaft diameter
number of pulses
and brand
Among other useful and important things in buying an encoder, the following can be mentioned. that if you do not pay attention to these points, the control of the desired position and speed will not be done or will be done incorrectly; And since these equipments have a very high price, if you buy them wrongly, you will suffer losses.
Number of wires and output type
Maximum allowed rotation speed
supply voltage
shaft type
encoder accuracy
rotation speed
The number of wires and...
Encoder type
In terms of general structure, they are divided into the following two categories:
Absolute Rotary Encoder
Incremental Rotary Encoder
Use of encoders:
Optical encoders are the most common and accurate types of encoders that are used in robots, packaging machines, etc.
Incremental encoders are used much more than absolute encoders due to ease of setup and output pulse.
The incremental absolute encoder is used to determine the position
Incremental absolute encoder is used to control speed, acceleration and movement direction
One of the applications of the multitrain rotary encoder is in tower cranes; When the crane is turned off, and the load is moved according to conditions such as wind, this error is stored in the encoder itself.
