Since it's summer and the group is kind of quiet I thought I'd post a link to a
short video I made last month. I bought a new tool cabinet for under my lathe
that ended up being about 1" too tall and I'd run out of room on one adjustable
foot to raise the lathe higher.
So I made a wooden

I converted similar sensors with a 10k resistor.

Well, you can't

No, that will cause excessive base current in the PNP
transistor. You need about a 10K resistor in series with
the PNP' base wire.

use a PNP transistor like so:

But why do you think you need PNP output? The device has an open collector
NPN output, just hook a resistor to whatever voltage you need (if your
system is using 24V for
