The TLP1211 photointerrupter combines a GaAs infrared LED, a Si phototransistor and an on‑board amplifier. It provides an open‑collector output that goes high when the light path is blocked. The device features a wide 12 mm gap suitable for detecting large objects and a polycarbonate case.
The datasheet lists maximum ratings, opto‑electrical characteristics, mechanical dimensions, and safety precautions such as torque limits for mounting screws and chemical incompatibilities with the polycarbonate housing.
