Optical Sensors - Phototransistors operate by converting light into electrical current, thus functioning as light-sensitive transistors. These sensors are widely used in light detection and ranging (LIDAR), safety systems, and ambient light sensing.

Manufacturers such as Everlight, Fairchild, and Broadcom provide a range of phototransistors suited for various applications. Their high sensitivity and fast response enable precise light detection tasks.

For applications where reliable and efficient light sensing is crucial, phototransistors are the go-to choice. Evaluate your needs to select the ideal phototransistor.
