GP1S522 Photoelectric Switch Sensor (GP1S522 Optical Sensor)
The GP1S522 Photoelectric Switch Sensor is a compact slotted optical interrupter designed for non contact object detection and position sensing. It consists of an infrared emitting diode and a phototransistor placed opposite each other within a molded slot. When an object interrupts the IR beam passing through the slot, the output of the phototransistor changes state, enabling precise switching and detection.
The GP1S522 sensor is widely used in India for embedded systems, industrial electronics, printers, and automation equipment. It is valued for its reliable detection, fast response time, and stable performance in applications such as encoder feedback, paper detection, and motion sensing.
