Proximity Distance is dependent upon emitter properties the reflective properties of the proximity reflecting surface. The nominal value shown
uses an IR emitter with a peak wavelength of 850nm and a 20° half angle. The proximity reflecting surface used is a 16” x 20” Kodak 90% grey
card. 60 mw/SR, 100 mA, 64 pulses, open view (no glass). Note: Greater distances are achievable with appropriate system considerations.
