Hi everyone,
i am new to this forum and really need some help to connect my proxy sensors.

I have the following breakout board:
DB25-1205 ( powered from external 5v DC psu)

https://forum.linuxcnc.org/media/kun...5DB25-1205.pdf

proxy sensors are the following:
Lj12A3-2-Z/AX NPN NC 3 Wire DC 6-36v

my plan is to use a 12v external psu to power all the 3 sensors which I intended to use for homing on my 3 axis. No limit switches will be added as I have set the soft limits. The reason I am changing to proxy as the traditional mechanical switches failed few times due to vibration when I was running a bigger tool on higher speed.

my plan was to either use:
- one sensor / input
-or all 3 sensor in series to one input.
I am using pin15 for e-stop so both option could work but i would like to make it as simple as possible.

after some research i've found if all 3 connected in series I need to use diodes and resistors which is not a problem. or if I use individual pins no need according to few related post.

if anyone could help me shed some light on this would be much appreciated, thanks.
