The inductive sensor I'm using is Amazon item # B00979RA1M. It's cheap and hasn't missed a beat. Anyone hooking these up needs to know some basic electronics. There are some good Youtubes on using this type of sensor.
Yes, I tried infrared sensors. Both direct and retro reflective.
I could not find an accurate way to count brass with optic sensors. Round and shiny makes a lousy target for a beam of light. Light beam width, reflections and distance could all throw off a count.
