Product Overview
The BWC Series Cross-Beam Area Sensor offers a minimized blind zone through a 3-point cross-beam netting method, providing a long sensing distance of 1 to 7 meters. It features a wide selection of 14 models with varying optical axis counts (4 to 20), optical axis pitches (40mm, 80mm), and sensing widths (120mm to 1,040mm). Designed for ease of installation with a dedicated installation mode, this sensor includes built-in interference protection and a self-diagnosis function. The self-diagnosis output monitors front screen contamination and optical axis obstruction, providing status information to external equipment. High luminance indicators on the emitter and receiver ensure easy status checks from various angles and distances. The BWC80-14HD model meets KRS Korean Railway Standards. Its robust IP67 protection structure makes it suitable for diverse environments, including use as an obstacle detecting sensor for subway platform screen doors (PSD).
