The TLP1243 (C8) is a compact photointerrupter with a built-in connector that uses a GaAs infrared LED and an Si phototransistor. Compared to Toshiba’s TLP1241 (C5), the volume and the mounting area of the TLP1243 (C8) are reduced to approximately 70% and 75% respectively.
The TLP1243(C8) is a compact infrared photointerrupter with a built‑in connector, designed for use in copiers, printers, fax machines, air‑conditioners, and game machines. It features a GaAs LED and an Si phototransistor, offering a 5 mm gap and a 0.7 mm slit width.
The datasheet lists absolute maximum ratings, typical electrical parameters, mechanical dimensions, recommended Mini CT connector, and precautions for handling and mounting. It also includes switching‑time curves and positioning guidelines for the shutter and device.
