OIER2 Reflective sensor - 1

General Description The OIER2 reflective sensor consists in a red emitting diode and a double NPN silicon phototransistor. The components together are mounted side by side in a plastic black SMD housing. The black package avoids light reflections, noise and behaves as a barrier between led and photoreceivers. The phototransistors respond to radiation emitted from the diode only if a reflective object surface is within the field of view of the detector. Applications Scanning Automated transaction systems Metering systems Motion control systems Non invasive medical equipment Low distance metering _ Features ■ Unfocused for sensing diffused surface ■ SMT package ■ High uniformity ■ Very stable measurements ■ High gain phototransistor ■ No contact surface sensing ■ Low profile ■ Low cost ■ Milling on the backside for side PCB mounting Function Phototransistor Collector Phototransistor Emitter LED Anode LED Cathode Ordering Information OIER2 Reflective Sensor with Red LED
