MOC7811 Slotted Opto Isolator Sensor (5V, IR Slot Type)

The MOC7811 Slotted Opto Isolator Sensor is an optical switching device designed for non contact object detection, position sensing, and motion measurement. It uses an infrared emitting diode and a phototransistor positioned opposite each other across a slot. When an object passes through the slot, it interrupts the infrared beam and changes the phototransistor output. This switching response makes the sensor suitable for encoder systems, counting applications, and automated equipment.
