This is a so-called “hand-sweep” sensor.
Supply it bewtween 5 and 24v DC input, and it will put that same input onto the output pins controlled by your hand.
Maximum current 3A
Sweep your hand across to turn on, sweep your hand across to turn off.
The maximum sensor distance is about 8cm
Perhaps the most obvious use for this sort of thing would be to turn on under-bench LEDs or something, just sweep your hand across to turn it on, sweep across to turn off.
