For a sensor with a sinking output, what is the output voltage when the sensor is activated?

Explanation:
A sinking output is designed to pull the output node to ground when activated. The load is connected to a positive supply, so current flows through the load into the sensor, which sinks it to 0 V. Therefore, the output voltage at activation is effectively 0 volts (ground potential), with only a tiny saturation voltage possible in practice.
