Using the QVE00033 surface mount phototransistor optical interrupter switch

The QVE00033, phototransistor optical interrupter switch, consists of an infrared LED emitter that is optically coupled to a phototransistor detector through a 0.4mm aperture on both sides. The emitter and detector are separated by a slot, 2mm wide and 3.7mm deep. The QVE00033 is configured in an SMD style and packaged in a temperature resistant black plastic housing for reflow soldering mounting.
