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.

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. |
