Re: Shooter consistency
I wanted to update this post with some more info we found yesterday.

While the S5 encoder from US digital states a maximum rpm of 10,000, they only state that is for the bearings. In practice, we're seeing a loss of signal around 8600-8800 rpm. The sensor will begin missing counts and you will see a drop in rpm feedback as you increase the speed of the motor above that.

As a backup, we tried one of the $12 allied electric photo switches (more info on specifics elsewhere - just do a search). They don't have a response time listed so we had low hopes, and it didn't work.

We then switched to allen bradley photo switches from 2011. We have half the wheel colored black, the other half with reflective tape. We have extremely good feedback up to our max speed of around 11,500 rpm.

It appears, however, that this sensor is not widely available anymore. Does anyone have a source with reasonable shipping times? Is there a drop-in replacement that anyone is aware of?
