@Veti They should be comparable, most voron designs are based on a PL-08N2 which has a 8 mm rated distance (0-7mm reliable).
The Omron M5Q-LT is the default for the switchwire and i happen to have 5 lying around from another project which has a range of 5mm (+-10%, 0-4mm range)
There accurate between there normal operating temperature, -20 to 70c
There all comparable to normal NPN sensors, these just are 10-24V rated so there connected to one of the fan slots and hooked up to the probe-in slot with a diode to protect that pin from any 24V feedback
