New cartesian 3D Printer Build

All, I am currently working on another build. I plan on using a probe for the Z and would like to know what the maximum voltage that the Z probe in pin can handle. My voltage is currently 4.62 VDC, will this be okay? I will be connecting at the Z probe in and ground on the z probe connector.

No, 3.3vdc is the maximum.

The Z probe input of the Duet WiFi is protected against over voltage, but if you are using resistors to reduce the output voltage of the sensor then I recommend you adjust them to limit the voltage to 3.3V or less. See https://duet3d.com/wiki/Connecting_a_Z_probe#PNP_output_normally-open_inductive_or_capacitive_sensor if it is a PNP output sensor.

Thanks , I will adjust my resistors accordingly.
