pull-up resistors

FAQ: What are encoder pull-up resistors, and how do engineers use them?

Thursday, December 10, 2015

To understand pull-up resistors, it helps to first understand how encoder output is generated. Incremental encoders can provide several types of digital output, with the three primary types…

Encoder Pulses Per Revolution

FAQ: How do I determine the required pulses per revolution for an encoder application?

Saturday, October 24, 2015

Incremental encoders determine rotary position by generating a specific number of pulses per revolution (PPR) and counting those pulses as the encoder spins. The PPR rating indicates resolution, and…

rotary encoder

FAQ: What’s the difference between single and multi-turn rotary encoders?

Thursday, October 15, 2015

Absolute rotary encoders output precise position information—even after a power-off condition—by assigning a unique digital value, or “word,” to each shaft position. But in applications where the encoder…

Resolver vs Encoder

FAQ: Why are so many designers replacing resolvers with encoders?

Friday, October 9, 2015

Resolvers and encoders are both devices that measure the rotary position of a shaft by converting mechanical motion into an electrical signal. Resolvers have a longer history, originally used…
