The typical application of these devices is a reflective or

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

information contained in its output. The TSSP4056 is also

suitable for fast (~ 5 ms) proximity sensor applications for

ranges between 10 cm and 2 m. Please see application note

“Vishay’s TSSP4056 Sensor for Fast Proximity Sensing”

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.
