3.1mm Slot Width Slotted Opto Interrupter Sensor (3.1mm Opto Interrupter)
The 3.1mm Slot Width Slotted Opto Interrupter Sensor is a compact optical switch designed for non contact object detection and position sensing. It consists of an infrared emitting diode and a phototransistor placed facing each other with a 3.1mm gap. When an object passes through the slot and interrupts the IR beam, the output changes state, enabling precise detection and switching. This transmissive sensing method ensures high reliability and fast response in electronic systems.
This slotted opto interrupter is widely used in India for embedded systems, industrial electronics, printers, and automation systems. It is valued for its accurate detection, high speed switching, and consistent performance in applications such as encoder feedback, speed sensing, and object counting.
