Abstract
A modular encoder with a dimensionally stable housing which can be easily aligned for mounting on a motor housing. The encoder utilizes a monolithic, in-line, sensor array and a single light source to achieve improved long-term performance and includes improved alignment means permitting a user to readily align the encoder with a motor. Pre-alignment of the mask and sensor assembly simplifies the alignment performed by the user.
