ABSTRACT:
A disc shaped element has a central hole of diameter corresponding to the diameter of a motor shaft upon which an optical encoder assembly is to be mounted. Coaxial with the central hole is a decreased diameter portion dimensioned to be received in a mounting member component of the assembly carrying the light source for the optical encoder. Exact coaxial centering of the mounting member carrying the light source is maintained by the disc shaped element while the mounting member is rigidly secured to the motor itself. Thereafter, the disc shaped element can be removed and the remaining components of the optical encoder assembled with assurance of proper alignment between the light source and the photo cell part of the assembly.
