FWIW, I've never tried the sensor below about 80KHz, but
it should work at lower speeds. But we know how that goes.
The sensor will work at 4.3V. I am not sure that 20mA would be enough. The LED when fully illuminated draws close to that, alone. Of course, it is off most of the time. If the supply can handle bursts greater than 20mA, you might be ok.
