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
