OPB848TX Datasheet PDF - TT Electronics/Optek Technology

●Description

●The OPB847TX, OPB847TXV, OPB848TX, and OPB848TXV each consist of a gallium aluminum arsenide LED and a silicon phototransistor soldered into a printed circuit board then mounted in a high temperature plastic housing on opposite sides of a 0.100 inch (2.54 mm) wide slot.

●Phototransistor switching takes place whenever an opaque object passes through the slot. Both device types have a 0.025 inch (0.635 mm) by 0.06 (1.52 mm) aperture in front of the phototransistor for high resolution

●positioning sensing.
