Area Fiber Optic Sensor RT-E40

Core Operating Principle

This is a specially designed fiber optic probe that works with fiber optic amplifiers to achieve large-area continuous detection. The light signal emitted by the fiber optic amplifier is transmitted through an internal multi-core fiber array to the end of the rod-shaped probe, where it is shaped by optical lens/light guide structures to form a continuous linear light curtain. Probes are used in pairs (transmitter + receiver). When an object blocks the light curtain, the light signal intensity at the receiver decreases, and the fiber optic amplifier detects this signal change and outputs a switching signal.
