I forgot to mention that these sensors are NO and not NC.

Hello Gents
I am trying to connect the NPN type proximity sensors to the X,Y and Z axis.
These NPN sensors operate from 6 V to 36 VDC.
I was informed that these sensors can be connected to both the high 24V and the low 5V?
If I power the sensor up with 24V and activate the sensor, by moving a metal object, to the contact point, the voltage drops to 0,8 V.
The schematic, which comes with and on the sensor, shows a resistor between the black and brown wires. I remember doing this on my MACH3 BOB and had to achieve around 5 V, when the sensor was activated. This was also with a 24VDC supply.
I`m just confused on how to connect it to both the 24V and 5V? This does not make sense to me and then a resistor can not be used at all, between the BLK and BRN wires.

Hello Gerry
Yes, I did see that in the schematic, but I was not sure about the resistor, which goes between the BRN and BLK wires on the sensor? I was under the impression that a resister is compulsory, or else the BOB will be damaged?
So If I power the sensor from my 24 V PSU and connect the BRN wire to POSITIVE, then the BLK wire must go to one of the X103 - X115 inputs and the BLU wire must go to the 0 V terminal on the BOB?
Thank you for responding.

It only shows a resistor if using PNP sensors on an NPN input.
The schematic in the manual shows brown to PS 24V, black to X103-X115 (or X210-X215), and blue to 0V on the UB1.
I'm far from an electronics expert, so can't offer any more than that.

Thanks Gerry
I will connect them like that.
