Voltage doesn't drop to zero

Bought two of these for a cnc project to use as a homing limit switch which it didn't work. It is NPN because the signal line does connect to the negative wire and it is NO because it switches when metal approaches it but the voltage doesn't drop to 0.it just stays at 5v which is the voltage I have running it. I have tried it at higher voltages and I get the same results. Same results for both sensors purchased.not happy.

Pros

Proximity Sensors

Cons

The switch may be prone to wear and tear over time, particularly in rugged environments, which could lead to premature failure or replacement needs
