ITR9608 4 Pin Opto Interrupter Sensor (ITR9608 Optical Sensor)
The ITR9608 4 Pin Opto Interrupter Sensor is a high speed optical switch designed for non contact object detection and position sensing. It consists of an infrared emitting diode and an NPN phototransistor placed opposite each other inside a slotted housing. When an object interrupts the IR beam, the phototransistor output changes state, enabling precise detection.
The ITR9608 sensor is widely used in India for embedded systems, motor position sensing, encoder systems, and industrial electronics. It is valued for its fast response, high sensitivity, and reliable operation in applications such as slot detection, paper sensing, and rotation monitoring.
