Note(s) and/or Footnote(s):
1. The specified light intensity is 100% modulated by the pulse output of the device so that during the pulse output low time, the light
intensity is at the specified level, and 0 otherwise.
2. Proximity Operating Distance is dependent upon emitter properties and the reflective properties of the proximity surface. The
nominal value shown uses an IR emitter with a peak wavelength of 850nm and a 20° half angle. The proximity surface used is a 90%
reflective (white surface) 16 × 20-inch Kodak Gray Card. 60mw/SR, 100mA, 64 pulses, open view (no glass). Greater distances are
achievable with appropriate system considerations.
