Fiber Optic Sensor

Fiber optic sensors are high-precision detection devices that use light transmitted through optical fibers to identify the presence, position, size, movement, or surface characteristics of an object. Unlike traditional photoelectric sensors, fiber optic sensors offer exceptional flexibility by separating the fiber optic cable from the amplifier, allowing installation in extremely tight, harsh, or high-temperature environments where conventional sensors cannot operate. With the ability to perform diffuse reflective, through-beam, top-sensing, side-sensing, and U-type slot detection, fiber optic sensors are widely used in automated machinery, packaging lines, electronics manufacturing, robotics, and precision inspection systems.

SUCH fiber optic sensor category includes a full range of fiber sensor amplifiers (Single Digital, Dual Digital, NPN/PNP/NO/NC), diffuse and through-beam fibers, rectangular sensing heads, high-temperature fibers, U-type probes, right-angle sensors, and specialty fiber optic detect heads designed for micro-object detection. Whether used for high-speed counting, label detection, edge tracking, part presence verification, or transparent-object detection, Fiber Optic Sensors deliver fast response, strong anti-interference performance, and long-distance stable sensing—even under vibration, dust, oil, or high-temperature conditions. Their modular structure, small size, and compatibility with PLCs and automation controllers make them an ideal solution for modern industrial sensing applications.
