Abstract
A modular optical encoder includes a housing, a rotatable cam-loaded cover, an emitter/detector module and a code wheel which is positionable upon the shaft of a motor. The code wheel is positioned automatically against the cover during attachment of the encoder to the motor to set the desired emitter and detector gaps. Once the code wheel is locked to the shaft, the cover may be rotated to disengage the cams and followers so that the code wheel is free to turn with the motor shaft.
