Product Announcement from ROHM Semiconductor, USA LLC
ROHM offers the standard RPI-1031 optical sensor that detects movement in 90° intervals using an in-house infrared LED, 2 phototransistors and light blocking mechanism.
A novel architecture is utilized for silent operation eliminating the need for soundproofing while increasing design flexibility. In addition, optical sensors are not susceptible to vibration or magnetic fields as are mechanical and magnetic 4-way sensors respectively resulting in greater reliability.
Ideal applications include mobile phones, TVs, digital cameras and camcorders.
- Detects movement in 4 directions
- Not susceptible to vibration (unlike mechanical sensors)
- Not affected by magnetic fields (unlike magnetic/hall effect sensors)
- Compact surface mount package
