2. Proximity Operating Distance is dependent upon emitter properties and the reflective properties of the proximity surface. The
intensity is at the specified level, and 0 otherwise.
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. 60 mw/SR, 100 mA, 64 pulses, open view (no glass). Note: Greater
distances are achievable with appropriate system considerations.
