PEC12R-4230F-S0024

Encoder, according to its application field and working principle, could be divided into mechanical, optical, Hall-effect encoder, inductive encoder, linear encoder, draw wire encoder, absolute encoder, incremental encoder and so on. Among them, the most common, reliable and widely used is incremental encoder. PEC12R-4230F-S0024 is one kind of incremental encoder.

Incremental encoder, as its name implies, is a kind of encoder which outputs the incremental value of displacement. It works with the combination of light-emitting diode (LED) and photodiode (Photoelectric Detecting), which can output pulse signal that correlations to the upward and downward movement of rotary elements, thus conveying distance information (as Pulse/Revolt). The installation of incremental encoder is widely used in controlling the speed of the motor, the angular displacement of the tool, and dynamically positioning and controlling the moving direction.

The most important application field of incremental encoder is motor control. For instance, in the instrument of motor speed control, the speed of the motor is feedback via incremental encoder, then the speed controller can adjust the running speed of the motor accordingly. In other words, the motor runs according to the signal feedback from the encoder, which guarantees the speedy and accuracy of control.

As for the working principle, the PEC12R-4230F-S0024 is an incremental encoder installed with photoelectric transducer, which works by emitting light (LED) and receiving light (Photoelectric Detecting). When the rotary element rotates, it will spin the slotted disc within the encoder counter-clockwise. This will interrupt the transmission of light between the LED and Photoelectric Detecting, which triggers the encoder to output pulse signal, indicating the change of position. This pulse signal could be added into a counter in the control unit according to the Basic Signal Cycle which the encoder will output each time it turns one circle, thus the running speed of the motor or system can be detected and controlled.

In conclusion, the PEC12R-4230F-S0024 is a kind of incremental encoder, usually for motor control, whose working principle is based on photoelectric transducer emitting and receiving interruption.
