This is because of the way the bl touch is designed. It contains a microprocessor that reads the hall effect sensor and emits a pulse to the arduino. The trick is the hall effect is triggered when the pin (which has a little magnet on the top) gets pushed close enough to the solenoid that it gets yanked up. This is highly repeatable assuming your environment is stable (no emp pulse guns, freeze rays, laser vision, etc.). This isn't at all like a hall effect based encoder which I believe is what you are thinking of when you are talking about analog."}}
