The TSSP940.. is also suitable for fast (~ 15 ms) proximity sensor applications for IR detector ranges between 10 cm and 2 m, if a burst pattern with variable intensity is used. IR emitter Separation to avoid crosstalk by stray light inside the housing There should be no common window in front of the emitter and detector in order to avoid crosstalk via guided light through the window.
