Source for Additional Gear Tooth Sensors

We’re kinda sorta building two machines in parallel and were hoping to make the drivetrains, at least, as alike as possible. For that, we need to buy another pair of the gear tooth sensors provided in the kit.

I’ve poked around a bit and didn’t see a thread about a source for these sensors and I’ll keep looking around still, but I’m curious if anyone might know where I can look.

Thanks.

You can get 'em here

Middle of the page just above the wheels. $25 each.

…I looked at that page, too. I must be losing it.

Thanks guys.
