AMT103 Rotary Incremental Encoder connected with Bricklet

[AMT103 Encoder - Bricklet]

Hello!

I recently procured an AMT103 rotary incremental encoder for a brushless motor.

The outputs of the encoder are the A, B, and X channels, as shown in this photo and the corresponding CMOS voltage square waveforms are presented in this photo. For my project, I use 2048 PPR.

I want to connect the outputs of the encoder on a Bricklet. What bricklet would you suggest for this application? I was thinking of the IO-4 Bricklet 2.0 as a choice. Would this work?

 

Thanks a lot!

I’m only getting an error when trying to view those photos, but I see no reason why the IO-4 Bricklet 2.0 shouldn’t be able to read a rotary encoder’s signals. The bricklet’s API has a function to read all four inputs at the same time, so you shouldn’t have a problem with signals changing while reading them.

The Industrial Counter Bricklet has a mode to read quadrature encoders like yours:

But it requires a higher voltage range that your encoder can provide. You could us a transistor at the outputs of your encoder to match the voltage level required by the Industrial Counter Bricklet.
