Sharp to Introduce the Industry’s Smallest*1 Photointerrupter*2

Will Contribute to Space-Saving Designs and Higher Performance in Electronic Equipment

Press Releases

Sharp Corporation has developed and will introduce the industry’s smallest photointerrupter, the GP1S396HCPSF, measuring just 2.26 × 1.4 × 1.6 H mm.

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, and manufacturers are demanding smaller sizes and improved detection performance in these devices.

The GP1S396HCPSF features the industry’s smallest package size thanks to thin-wall molding technology developed over long years of experience in the electronic device field, and will contribute to making electronic equipment slimmer and more compact based on space-saving designs. In addition, the detection area has been reduced by achieving a slit width*3 of 0.12 mm, the industry’s narrowest (approximately 40% smaller than the predecessor model*4), thereby improving detection accuracy. Also, enlarging the gap between the emitter and receiver, which represents a trade-off with making the device more compact, to 1.2 mm (predecessor model*4: 1.0 mm) provides greater flexibility in terms of the target objects that can pass between the emitter and receiver.

Product name Subminiature photointerrupter
Model name GP1S396HCPSF
Sample price (tax included) 50 yen
Mass production date October 29, 2010
Monthly production 1,500,000 units

Major Features

1. Industry’s smallest package size (2.26 × 1.4 × 1.6 H mm).
2.   Industry’s narrowest slit width of 0.12 mm provides high detection accuracy (approx. 40% smaller than predecessor model).
3. Gap between emitter and receiver is enlarged to 1.2 mm (predecessor model: 1.0 mm), providing greater flexibility in terms of the target objects that can be detected.
*1 For subminiature photointerrupters, as of September 24, 2010. Based on Sharp research.
*2 An optical sensor that integrates an infrared light emitter and receiver in a single unit. The receiver detects the fact that a target object has blocked light from the emitter.
*3 Width of the long, narrow opening for light made in the receiver to improve accuracy in detecting the presence of an object.
*4 Sharp’s predecessor model: GP1S296HCPSF.
