I'm thinking thru holes perpendicular to the tube. I will probably place sensors both at the bottom and top of the tube. The top fiber switch can turn on the feed mechanism (absence) and the bottom sensor can stop the production line if the tube is near empty (absence). I assume the switch can...
I was more thinking along the lines of drilling a small hole or thru hole and using a fiber optic sensor. Triggering when light is visible on the other side, but having no experience in this I need advice on components and mounting, etc.
I need to detect presence/absence of small rifle primers stacked in a vertical stainless tube.
Tube ID is approximately .185", OD is approximately .3125"
Primers in the tube are .175" in diameter and .12" tall.
What would you recommend for sensor and how to mount on a round tube to detect...
