OSKS0805C1E is a body-mount, surface-mounting photointerrupter, made by Optosupply. It features a plastic housing in an SMT package, with two built-in light-emitting diodes (LEDs) and a dedicated, charge-coupled phototransistor. The package features an infrared-sensitive face, comfortable to use in any environment, while its extremely low profile (just 0.8 mm) makes it perfect for installation in tight space. The photointerrupter is able to detect transparent objects within a range of 5 mm, with a 0 V to 5 V output.
