De scrip tion
The OPB853A series of slotted optical
switches consist of an infrared emitting
diode and an NPN silicon
photodarlington. They are mounted on
opposite sides of a 0.125" (3.18 mm)
wide slot. The emitter has a 0.050" X
0.050" (1.27 mm X 1.27 mm) molded-in
aperture while the photodarlington has a
0.010" X 0.050" (0.254 mm X 1.27 mm)
molded-in aperture.
