Optical Displacement Sensors

June 30, 2009

OD precision optical displacement sensors connect three sensors to one controller, which reduces the amount of hardware required and eases the measurement of X-, Y- and Z-axes. The sensors use complementary metal-oxide semiconductor (CMOS) technology for detecting targets that are highly reflective or have dark remission characteristics. The sensors require no software and can be used in stand-alone mode. The sensors have 0.02-micron resolution, appropriate for applications in the automotive, robotics and electronics/semiconductor markets. These sensors can verify machining tolerances, confirm part quality and positioning, and detect the thickness of glass in solar panel manufacturing.
