Fits Better Packages BP555e model gummed tape dispensers. The reader is adjustable by loosening the screw and slightly moving to better read the gaps in the encoder wheel.
These can break when the feed wheel sprocket comes loose from the shaft, and the shaft is able to rock back and forth while dispensing. This cracks the encoder reader.
When installing a new encoder reader, be sure to route the wire carefully so that the screw from the side frame does not drive through the wire. The factory winds the wire between the nuts for the idler shaft and yoke to help keep the wire away from that screw hole.
