PHOTOINTERRUPTER
Photointerrupter
Photo IC output
P6291
P6921 is a photointerrupter consisting of a high-power infrared LED and a photo IC. The photo IC incorporates a high-sensitivity photodiode, an
amplifier, a Schmitt trigger circuit and an output transistor, all integrated in a single chip. These elements are enclosed in a miniature C-shape
plastic package with a gap of 1.2 mm and a slit width of 0.2 mm, allowing object detection with high precision.
