L14G2 Phototransistor Photo transistor FAIRCHILD SEMICONDUCTOR L14G2

Product Overview

The L14G2 is a silicon NPN phototransistor housed in a hermetically sealed TO-18 package with a glass lens. It is designed for high-sensitivity detection of infrared and visible light radiation. The optical lens provides a narrow acceptance angle, making it highly directional and minimizing optical crosstalk from ambient light. It is commonly used in industrial automation, optical switches, object counters, encoders, and infrared light beam detection systems.
