20000ppr high resolution rotary encoder push pull output complementary signal output KN40
1. for 1-10 samples: 3-5 working days
2. for 20-50 mass production: 7-10 working days
3. for over 100pcs, production will be discussed with customers and ship on time
Notice for encoder installation
1. Please read the encoder specification carefully before installation
2. Encoder is belong to precision instrument, so we should avoid shock or vibration to protect interior parts.
3. The power supply voltage must be holded within specified range, or encoder could be destroyed.
4. Notice coaxially requirements when you install the power shaft, please use flexible coupling and do not press encoder forcibly.
5. Shielding cable of encoder must be connected to avoid electromagnetism interference of alternating current, cables of encoder should be layout individually.
6. Wiring diagram connection should be strictly follow the specified color in catalogue, or encoder interior circuit may be destroyed
7. Encoder should be apart from powerful magnetic field, dust, oil, water, higher (lower) temperature and caustic or flammable material during working.
8. The encoder cable signal can’t be drew or bent forcibly.
Principle of encoder
An incremental encoder outputs a defined amount of pulses per revolution, so that every pulse is expected to be on a defined mechanical position. The maximum deviation between this ideal position and the actual position is called integral non linearity (INL). The INL accuracy is an important value if the incremental encoder is used for positioning tasks.
The duty cycle describes the ratio between “high” time to “low” time of an incremental encoder. Typically this ratio is 50/50, which is equivalent to 180 el° high and 180 el° low.
The performance of magnetic incremental encoders increases with higher PPR settings and higher rotation speeds (RPM). This is in contrast to optical encoders where the performance decreases. The DNL and INL accuracy that are stated in our datasheets are worst case values, a better performance can be expected for higher PPR and RPM.
This is the maximum frequency that the encoder is able to output via the output lines.
For example, the frequency of a 1024 PPR encoder that rotates at 600 RPM is 200 Hz (200*1024/60s).
