How to select an encoder?

Before you determine to order a rotary encoder, here are a few questions that may help to make the best decision.

A. Do you need an incremental encoder or an absolute encoder?

B. What is the signal output and power supply voltage?

C. What resolution does the application call for?

D. How to mount this encoder and how to connect the encoder to controls?

E. What environmental and mechanical stresses does the encoder need to bear?
