Cross-Beam Area Sensor
The Cross-Beam Area Sensor offers a minimized blind zone through a 3-point cross-beam netting method, enabling long sensing distances from 1 to 7 meters. It provides a wide range of model choices with varying optical axis counts (4 to 20), optical axis pitches (40, 80mm), and sensing widths (120 to 1,040mm). Features include an installation mode for easy setup, built-in interference protection, and a self-diagnosis function that monitors front screen contamination and optical axis obstruction, providing status information to external equipment. High luminance indicators on the emitter/receiver ensure easy status checks from various angles and distances. The sensor is suitable for Korean Railway Standards (BWC80-14HD meets KRS conditions) and is utilized in diverse environments, such as an obstacle detecting sensor for subway platform screen doors (PSD).
