Technical Data Sheet Opto Interrupter Features Fast response time High analytic Peak wavelength λp=94nm High sensitivity Pb free This product itself will remain within RoHS compliant version. DS-31MM Descriptions The 31MM 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 does not receive radiation from DR LED in normal situation, but when an object comes closer, the radiation is reflected by the object and phototransistor receives the more radiation as closer the object comes. For additional component information, please refer to DR and DT.
