What is the line driver output of optical rotary encoder ?！

Optical rotary encoder line driver also calls the difference for the long term driver, 5 v, the positive and negative waveform symmetry of TTL, due to the line driver of line driver positive and negative current in the opposite direction, external electromagnetic field offset, so the anti-interference ability strong.Normal encoder generally transmission distance is 100 meters, if it is 24 v HTL and symmetric negative signal, transmission distance, 300-300 m.
