The XL-ITR8102 Slotted Optical Sensor is a compact slot-type photointerrupter designed for accurate object detection, position sensing and motion control in electronic and automation projects. Supplied as a through-hole device, it is easy to mount on PCBs, making it ideal for prototyping, robotics and embedded control systems.
The sensor integrates an infrared LED emitter and a phototransistor receiver positioned opposite each other across a narrow slot. When an object or interrupter passes through the slot, the infrared beam is blocked, causing a change in the output signal. This simple but reliable sensing method allows the device to detect movement, count rotations or determine position with high accuracy.
Commonly used in rotary encoders, speed measurement systems, counters, 3D printers, robotics and mechanical position sensing, the XL-ITR8102 provides dependable performance in a small and economical package. Fully stocked in the UK, it is available for fast dispatch for both hobbyist and professional electronics applications.
