Product Overview
The BWC Series Cross-Beam Area Sensor offers a minimized blind zone through a 3-point cross-beam netting method, enabling a long sensing distance of 1 to 7 meters. It provides a wide range of model choices with varying optical axis numbers (4 to 20), optical axis pitches (40mm, 80mm), and sensing widths (120mm to 1,040mm). Key features include an easy installation mode, built-in interference protection, and a self-diagnosis function that monitors front screen contamination and optical axis obstruction. Conspicuous high luminance indicators on the emitter and receiver facilitate easy status checks from various angles and distances. This sensor is suitable for applications such as obstacle detection for subway platform screen doors (PSD) and meets Korean Railway Standards (KRS) for specific models (BWC80-14HD). The protection structure is rated IP67 (IEC standard).
