Resistor for open collector-collector transistor

I have an encoder,; the circuit is in the image below:

Datasheet

The one that I’m interested in is the PNP one. I want to use a 0-5 V digital voltage, the datasheet says this:

  1. Applied voltage: 30 VDC max.
  2. Source current: 35 mA max
  3. Residual voltage: 0.4 V max. (at source current of 35 mA)

By my calculations with basic kirchhoffusing Kirchhoff's law I cannotcan't obtain 5 V because of the 35 mA max,max; the pulldownpull-down resistor should be very low, because the emitter resistor is very low. Am I missing something, how? How can I dimension the correct resistor correctly?

This wasis the calculationscalculation that I made, what wasis wrong I'm very tired:?
