The PITTMAN® 35mm ROSE (Reflective Optical Sensing) incremental encoder for brush-commutated and brushless DC motors has been awarded U.S. Patent No. 6,963,064. Instead of requiring discrete modules for individual line-count applications, this newly patented encoder provides an unprecedented capability to achieve multiple line counts utilizing only one module.
The PITTMAN encoder has been configured to fit a variety of brush-commutated and brushless DC motor products available from most manufacturers. Encoders can be added to any motor or gearmotor with wires or side-exiting power terminals and can be plastic-housed or open air. They can be factory-mounted or prepared for mounting in the final stages of end-product assembly.
This encoder features an innovative PC board-based modular design and multi-tracked code discs to enable the widest range of resolutions (192, 200, 250, 256, 360, 400, 500, and 512 counts per revolution) using minimal parts. The PC board consists entirely of surface-mount components, which promotes flexibility in low tooling costs and quick turnaround to accommodate custom control electronics.
The encoder is an incremental, non-contacting rotary-to-digital feedback device translating real-time shaft angle, speed, and direction of rotation to TTL-compatible outputs. Outputs are two-channel, in quadrature, with medium resolution encoding. Signal conditioning options (all on board) include an RS-422 high-speed differential line driver, pull-up resistors, and additional filtering capacitors.
