OPB847TX - TT

OPB847TX High Resolution Slotted Optical Switch

The OPB847TX consist of a gallium aluminum arsenide LED and a silicon phototransistor, which is soldered into a printed PCBoard and then mounted in a high-temperature plastic housing on opposite sides of a 0.10 inch (2.54 mm) wide slot. Both device types have a 0.025 inch by 0.060 inch (0.635 mm by 1.524 mm) aperture in front of the phototransistor for high.

Features

• Non-contact switching
• Apertured for high resolution
• Hermetically sealed components
• TX devices processed to MIL-PRF-19500 Description: The OPB847TX consist of a gallium aluminum arsenide LED and a silicon phototransistor, which is soldered into a printed PCBoard and then mounted in a high-temperature plastic housing on opposite sides of a 0.10 inch (2.54 mm) wide slot. Both device types have a 0.025 inch by 0.060 inch (0.635 mm by 1.524 mm) aperture in front of the phototransistor for high resolution positioning sensing. Phototransistor switching takes place when an opaque object pass.
