The model RB22 is an optical shaft encoder in a 2" diameter x 1-7/8" (Ø51mm x 48mm) housing with an integral mounting arm, compatible with a variety of mounting accessories for installation either above or below a moving web or conveyor. When used with the MW-8 (8.00" circumference) or MW-20 (20.00cm circumference) measuring wheels it can accurately track the web or conveyor to within ±.007" or ±.016cm per revolution. This is not a light duty encoder - it was built with heavy duty bearings and solid construction for reliable, long-term operation in continuous duty applications.
