Understanding Encoder Resolution

An encoder is a device that converts motion into an electrical signal. In a rotary encoder, the resolution determines how precisely it can measure rotation. This is defined by PPR.

PPR (Pulses Per Revolution): This is the number of pulses the encoder generates for one complete 360° turn of its shaft. A higher PPR means higher resolution and more precise position measurement.
Degrees per Pulse: This tells you the smallest angle of rotation the encoder can detect. It is simply 360° divided by the PPR.

Frequently Asked Questions (FAQ)

What is the difference between PPR and CPR?

PPR (Pulses Per Revolution) refers to the number of output pulses from one channel (A or B). CPR (Counts Per Revolution) usually refers to the number of states after quadrature decoding, which is 4 times the PPR. For example, a 1000 PPR encoder has 4000 CPR.

Which resolution do I need?

It depends entirely on your application. For simple speed measurement, a low PPR (e.g., 100-500) might suffice. For high-precision positioning in robotics or CNC machines, a high PPR (e.g., 10,000 or more) is often required.
