Sharp announced Smallest Photointerrupter
Sharp has announced industry’s smallest photointerrupter, with codename GP1S396HCPSF measuring just 2.26 × 1.4 × 1.6 H mm. Sharp achieved smallest package size, thanks to thin-wall molding technology developed over long years of experience in the electronic device field.
Subminiature photointerrupters are used to control the optical zoom of digital cameras, and to track the position of the lens for controlling the optical pick-up unit in Blu-ray Disc recorders. This breakthrough technology will contribute to making electronic equipment slimmer and more compact based on space-saving designs. Moreover Sharp has made possible reduction of the detection area and achieving a slit width of 0.12 mm, the industry’s narrowest, which is approximately 40% smaller than the predecessor model, thereby improving detection accuracy.
