Proximity sensor mounting base

Post by acourtjester »

I switched from micro switch to proximity sensor for the home/limits on my table. The ones I used were flat plastic housing type as show in the images. They can be bought in either switching common (NPN) or switching a voltage (PNP) shown in the attached diagram. I used the PNP with the Mesa card I used for the controller electronics. Attached is the STL file for printing your own, the holes can be threaded with a 10-32 tap for mounting.
I used the tip of a 10-32 machine screw to trip the sensor. Here are 2 different mounting brackets to chose from, the longer one has brass inserts.

Now that is cool Tom! Are you using Fusion to do your 3D models for your 3D printer?

No I use 123D Design it is a simple convert from DXF to STL program, I do want to learn Fusion 360 but this has done all I have needed to this point. It is not a precise as 360 but work very well.

Awesome, thanks Tom I will check out 123D Design. If it's getting the job done then thats all that counts, Fusion is awesome but if you don't need it then why bother. Too much stuff to remember.
