Side-Looking Reflective Sensor ITR20904 █ 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 silicon 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 reflecting object close to ITR, phototransistor receives the reflecting radiation and the different distance have different light current. █ Applications ․Printer ․Switch Scanner ․Non-contact Switching Everlight Electronics Co., Ltd.
