The typical application of this device is a reflective or beam

break sensor with active low “detect” or “no detect”

information contained in its output. The TSSP570.. is also

suitable for fast (~ 15 ms) proximity sensor applications for

ranges between 10 cm and 2 m, if a burst pattern with

variable intensity is used.

Example for a sensor hardware:

There should be no common window in front of the emitter

and detector in order to avoid crosstalk via guided light

through the window.
