Rotary encoders are a class of sensors used to detect the angle of rotation and its derived mechanical parameters, including velocity and acceleration, etc., and can detect transmission movements such as rotation and linear lines. Due to their wide range of applications, rotary encoders convert mechanical inputs into electrical signals that can be processed by counters, tachometers, programmable logic manipulators, and industrial PCs. Modern rotary encoders can be found in many mechanical and automated factories.
Rotary encoder application
(1) The application of logistics packaging occupation
With the development of the world's technology, the logistics profession is using more and more different equipment, and the supply of rotating sensors is becoming more and more effective, such as the confirmation of positive bearing and the measurement of speed. Rotary encoders are used in every part of the printing process and in every step, and the encoders are very resistant to oscillations and shocks.
(2) The application of the elevator profession
In the door control and elevator professions, encoders are dedicated to improving work efficiency, cutting error rates, and are used for speed measurement, as well as synchronous and positive bearing measurements.
1. Door azimuth measurement control car azimuth measurement 2. Synchronization of handrails and stairs 3. Rotation direction monitoring
(3) The use of wind power generation occupations
There is a huge market for wind power generation in China, and with the rapid development and development of various wind power generation equipment technologies, we can rely on P+F encoders to make their own contributions to this profession.
1. Control and detection of wind wheel speed 2. Measurement and control of wind wheel blade angle 3. Control and measurement of yaw angle

Important features of our sensors
On the linear scale of our sensors, the higher the sensitivity, the better. Because only when the sensitivity is high, the value of the output signal corresponding to the measured change is relatively large, which is conducive to signal processing. However, it should be noted that the sensitivity of the sensor is high, and the external noise that is not related to the measurement is also simple.
