ITR1203DT50A/TB
Features
․Fast response time
․High analytic
․High sensitivity
․Pb free
․This product itself will remain within RoHS compliant version
Description
․The ITR1203DT50A/TB consist of an infrared emitting diode and an NPN silicon phototransistor, encased side-by-side on
converging optical axis in a black thermoplastic housing,
․The phototransistor receives radiation from the IR LED only .This is the normal situation.
․But when an object is in between, phototransistor could not receive the radiation.
