The SICK WL12-2N120 Through-Beam Photoelectric Sensor is a through-beam detector from SICK that detects object presence by beam interruption between an emitter and receiver. The part number WL12-2N120 indicates the device is configured for industrial automation applications where objects on conveyors, packaging lines, or tooling setups are monitored. In a through-beam configuration, the emitter sends a light beam to the receiver, and any interruption of that beam signals a detected target.
