Ok, here's the encoder's datasheet. And here's my question: Would the following adaptation of your circuit (no cap this time, for your great relief...), as shown in the figure below, be adequate to receive the signal from that encoder through a shielded wire 20m long, assuming that the frequency remains below 100 Khz?Start a new thread. Include the datasheet in the post. Make it a new discussion.
Would a value for R3 of 4.7k be acceptable if the signal is a square wave of 0 to 5V, push-pull, 4ma max?
Note: In my application, direction of rotation is not important, so I plan to XOR the encoder's two quadrature outputs to obtain a single square wave. As shown in the attached simulation.
