Title: Rotary Encoder
Post by: drinu on March 17, 2014, 03:23:28 PM

Hi,

I am interested in buying the rotary encoder in the link below. The specs states  that it can be supplied with 5V to 24V. Does that mean that I can operate the encoder with 5V or is that referring to the signal (collector) pin voltage range?
Also, does rotary encoders of this type create debouncing?

Thanks in advance.

Hi
You should be able to power it from a 5-24V source on the VCC pin.

You should not need to debounce an encoder, you can plug it directly into your motor controller (or encoder input interface).

I think the note about not connecting VCC to an AB channel is just a warning not to short an input pin to VCC or you can damage the sensor.

Thanks for the reply. Is a 1kohms pull up resistor enough to connect with pin a and b?

You can normally just connect the A and B channels to your motor-controller/encoder-interface with no pull up resistors.
