Note(s):
1. 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 850 nm and a 20° half angle. The proximity surface used is 90%
reflective (white surface) 16 × 20-inch Kodak Gray Card. 60 mw/SR, 100 mA, 64 pulses, open view (no glass). Greater distances are
achievable with appropriate system considerations.
