TXC announces a new series of miniature 4-in-1 Light Sensors (Color and Proximity Sensor with IR VCSEL integrated) (PA22C product series) TXC Corporation

This newly developed 4-in-1 sensor consists of an Color Sensor, and a Proximity Sensor with IR VCSEL diode and an integrated photo detector and control circuits. All of the above standalone components are packaged in a 2.5x2.0x1.0mm patented, multi-layer ceramic package for better optical mechanical design without the need for extra lens.


The special features of this product includes (1) Small size: 1/2 of the size compared to conventional 4.0x2.4x1.35mm3 products, (2) Low power consumption: IR VCSEL only consume 1/10 of the power compared to conventional IR LED, and (3) Widest Field of View (FOV): with patented multi-layer package design, FOV can be increased from +/-30 degree to +/-50 degree – which is the largest FOV for 4-in-1 sensors. With the above advantages, PA22C is especially suitable for smartphone, tablet, digital camera and smart wearable devices applications.
