TLP1033A is a red infrared optical switch launched by Toshiba. It is mainly used in household appliances, copiers, printers, fax machines and other OA devices, as well as automatic vending machines and ticket machines. The product adopts high light output GaAs infrared LED and high sensitivity, high gain, high voltage Si photodiode, with low power consumption, high reliability and other characteristics.
The TLP1033A is a photointerrupter that combines a high‑output GaAs infrared LED with a high‑sensitivity, high‑gain, high‑voltage photodiode, delivering a digital open‑collector output. It is intended for use in consumer electronics, office equipment, vending machines and position‑detection applications.
