side-looking reflective sensor ITR20904 everlight electronics co., ltd. 1 http://www.everlight.co m document no drx-0000028 rev 1 june. 05, 2009 features ? side-looking package ? fast response time ? miniature and thin ? high sensitivity ? cut-off visible wavelength descriptions the dip type ITR20904 consists of an infrared emitting diode and an silic on phototransistor, encased side-by-side on converging optical axis in a black housing. the phototransistor receives radiation from the ir only. this is the normal situation. but when a refl ecting object close to itr, phototransistor receives the r eflecting radiation and the different distance have different light current. applications ? printer ? switch scanner ? non-contact switching
