Opto Interrupter ITR9608 DIP-4 Overview This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes between the uprights, breaking the beam. Used for many applications including optical limit switches, pellet dispensing, general object detection, etc. Gap width = 5mm. Features Fast response time High analytic Cut-off visible wavelength λp=940nm High sensitivity Pb free This product itself will remain within RoHS compliant version
