New Renco Radial Line Sensor Array Ends Inter-Channel Jitter.

AN OPTICAL ENCODER IS ONLY AS GOOD AS THE CUMULATIVE ERRORS OF ALL THE COMPONENTS.
Until now, you had to live with the inherent angular separation error caused by placing the encoder's
photosensors along the circumference of the disk. The separation error magnified the effects of
disk runout and eccentricity, and made inter-channel jitter inevitable.
ACCURACY: ± 2 ARC MINUTES.
Typical quadrature tolerances are 90 ° &plusm; 22.50° which provides easier installation of modular kit encoders, and additional fine tuning to 90° &plusm; 9° is available. So you can specify simpler circuitry and lower class bearings, yet maintain accuracy.
RESOLUTION: I TO 5000 LINES.
22 standard resolutions are available--20 of them indexable. All disks are dynamically centered to the centerline of the hub or Shaft to four-decimal concentricity of data track.
12 YEARS OF OPTICAL ENCODER RESEARCH.
RENCO understands encoders. We've been researching the measurement of incremental motion and its conversion to digital logic since 1968. Our parent company, Electro-Craft, gives us an intimate understanding of motion control systems and the problems and needs of the systems designer. We manufacture absolute and incremental shaft encoders, linear encoders, and modular kit encoders. We have the one you need for your specific job.
