Shadow Technology

You thought our reticle on a chip was revolutionary

Design Features:

  • Improved common mode noise rejection due to enhanced differential sensing
  • Reduction of physical size of the sensor
  • Lower assembly cost
  • Reduced LED columnation requirements
  • Increased airgap
  • Reduced disk manufacturing requirements
  • Elimination of balancing potentiometers
  • Interdigitated Index Channel

 

Shadow technology sensor designs provide several distinct advantages over traditional differential sensing encoders systems. The ability of this technology to discriminate typical optical system errors as common mode noise increases performance and reliability while simplifying manufacturing requirements for optical encoders.

Shadow technology sensors offer simplified encoder assembly due to the improvement in sensor/code wheel alignment tolerance. Simplified assembly results in reduced manufacturing costs. The code wheel light transfer constancy and mechnical system inconstancies become less of an issue and result in less field failures and more satisfied customers. The bottom line is improved as the encoder manufacturers enjoy a higher profit margin and improved competitive edge.
