Ambient Light Sensing Phototransistors IR (PT-A2-AC-850)
With RoHs compliant, DeMint phototransistors are available in a wide range of packages.
A phototransistor is known as a device in which turns light source energy into electric energy. Phototransistors are very close to photoresistors but produce both current and voltage, while photoresistors simply produce current. The reason is a phototransistor includes a bipolar semiconductor and targets the energy this can be transmitted via it.
Phototransistors are light-sensitive transistors. A common type of phototransistor resembles a bipolar transistor with its base lead removed and replaced with a light-sensitive area. This is why a phototransistor has only 2 terminals instead of the usual 3. However, when the light-sensitive region is exposed to light, a small base current is generated that controls a much larger collector-to-emitter current.
DeMint PT-A2-AC-850 family with environmentally friendly photosensitive sensors, control sensitivity under low illumination, stable current signal output under strong light source. Multiple light at the same time can be used to ensure consistent photosensitive effect, not false trigger. Meet the latest environmental requirements of toys. Applicable to all kinds of light control lighting products (such as night lights, lawn lamps, solar lights, etc.), automatically adjust the background light (such as LCD, mobile phones, cameras, computer cameras, security monitoring machines, etc.).
The PT-A2-AC-850 ambient light sensor, commonly used in infrared reception, Ultra-thin multi-point infrared touch screen, and all kinds of high-light or visible light interference strong products, such as various types of infrared light control, infrared on the radio, infrared reflection and other electronic products.
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.
