    Description

    The ST-1KLA Highly Sensitive Silicon Phototransistor is a precision-engineered TO-18 package light sensor designed for high-performance infrared detection and optical applications. Featuring a hermetically sealed metal cap enclosure, it provides superior protection against humidity, dust, and environmental interference, ensuring exceptional reliability in industrial and outdoor setups. With a narrow half-value angle of 6° and a high minimum photocurrent of 1.5mA (at 10V, 200lx), the ST-1KLA offers excellent directional light detection suitable for automation, optical switching, and security devices. Its stable characteristics and minimal signal degradation over time make it ideal for long-term operation in demanding applications such as safety equipment, automatic doors, encoders, and banknote authentication systems. Engineered for accuracy, sensitivity, and longevity, this phototransistor is a preferred choice for designers seeking consistent infrared sensing performance. Featured By RoboticsBD.
