SG105F Photo Interrupter Sensor (SG-105F Optical Sensor)
The SG105F Photo Interrupter Sensor is a compact reflective optical sensor designed for non contact object detection and position sensing. It integrates a GaAs infrared emitting diode and a high sensitivity phototransistor in a single package, allowing it to detect objects based on reflected IR light intensity changes. This super mini design ensures efficient operation, fast response, and reliable performance in space constrained electronic systems.
The SG105F sensor is widely used in India for embedded systems, automation equipment, and industrial electronics. It is valued for its compact size, high speed response, and stable detection capability in applications such as edge detection, timing systems, and liquid level sensing.
