Encoder System suits portable, electronic devices.

Press Release Summary:

Model KP-1SM100 is based on laser rotary encoder technology. It obtains significant temperature characteristics by employing digital servo controllers and encoders with diffraction interference systems that utilize diffraction of laser beams. Scanning angle is ±10° and rotor inertia is 10.5 gcm-sq with 30 mm diameter mirror, resulting in positioning resolution of .02 arc sec. System can be used in miniaturized, high density PC board manufacturing.

Canon U.S.A. Introduces Motor Encoder and Controller System

Ultra Compact, Applicable For Portable Electronic Devices LAKE SUCCESS, NEW YORK, April 8, 2003 - The Semiconductor Division, Encoder Products Group, of Canon U.S.A., Inc., a subsidiary of Canon Inc. (NYSE: CAJ), has introduced a new encoder system for use in miniaturized, high density PC board manufacturing. Particularly applicable for portable electronic devices, the new ultra compact system is complete, including a controller and a specialized KP-1SM100 motor encoder. The Canon KP-1SM100 system's precision control of laser beam scanning through high inertia mirrors makes it extremely cost-effective for laser marking and laser processing applications. The new system is based on Canon's leading-edge laser rotary encoder technology and it is ultra compact. It features a high scanning angle (±10°) and rotor inertia (10.5 gcm-sq.) with a 30mm diameter mirror. This results in a positioning resolution of .02 arc seconds (or less). Torque constant is 0.10 Nm/A. Miniaturized environments can create excessive temperature environments. Unlike the performance degradation and downtime observed with laser scanners that employ galvanometers for beam control, the Canon KP-1SM100 obtains significant temperature characteristics by employing digital servo controllers and encoders with diffraction interference systems that utilize the diffraction of laser beams. The scanners achieve high positioning accuracy of 0.5 µrad (microradians (*1) or lower, and accelerate to settling speeds (*2) of 0.7 msec./0.3° and a settling range of ±215 µrad. They contribute significantly to cost reduction and increased uptime at the manufacturing site when incorporated into laser board-processing equipment. The new system also has applications in other high precision areas, including laser trimmers, LCD repair devices, rapid prototyping machinery that generates three-dimensional models directly from 3D-CAD data and optical spectrum analyzers for optical communications.
