SMD Infrared Receiving Light Sensor (PT-B1-DC-0603-940) Chip
Direct SMD IR phototransistors achieve the second generation of optical axis keyboard.
Optical axis keyboard is a new generation keyboard which join the new optical sensor recognition technology in recent years. By replacing the traditional metal contacts for the optical sensor components, use optical media as a bridge. Because there is no contact, so it will not wear.
Optical axis technology takes advantage of infrared optical induction. There is no abrasion during conduction due to no contact point. The waveform of Optical signal pulse output is clean and noise-free. The keyboard response speed only takes 1ms. Thanks to the new optical sensors - SMD IR phototransistors (PT-B1-DC-0603-940) is the most critical component in optical axis applications.
The (PT-B1-DC-0603-940) surface mounted infrared receiving light sensor features fast response speed, stable performance, low current loss in static, and anti-strong light interference. The effective control distance is greater than 1.5 meters.
For the convenience of installation in all kinds of products in any position, different sizes are available upon request. So that product consistency is better, more market competitiveness. It is also achievable to provide the bright current / dark current (bright resistance / dark resistance) for the most suitable product.
