Wms blade stepper big top wheel sensor

[WmsWizard]

I'm looking for the sensor for the top wheel or even a part number

Where is it broken?  It might be easier to just fix it or rig it.
I checked ebay and found some close matches, maybe you can modify these.
Google might have been a better search.. But used eBay because I was looking for one the other day, a different model...
"Optical Interrupter"

They are basically an ifrared LED and a light sensor,  the sensor rarely goes bad but the LEDs fail, or just replace the whole thing.

I was going to remake this PCB but have not got to it yet.  Mine showed up in two pieces some years ago and had to solder it back.
I also blew up the microcontroller and replaced it.  That was my first one.  Had to reflash it too.  Gawd what a pain in the ass it was.
Old technology, old hardware, old old old

I was going to make a mini-wheel.....

Hopefully these members will chime back in (and be grateful!) as you're replying to year old posts.
However it would be BETTER if you could add a photo with those links.
Believe me, in a few months or a year... something like this will show up!
