Features Inexpensive opaque plastic housing 0.125" (3.18 mm) wide slot 0.290" (7.37 mm) lead spacing Apertured for high resolution Photodarlington output Description
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.
