Key Attributes
Model Number:
BWC40-18H
Product Description
Product Overview
The BWC Series 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 (40mm, 80mm), and sensing widths (120mm to 1,040mm). Features include easy installation with an installation mode, built-in interference protection, and a self-diagnosis function that monitors sensing front screen contamination and optical axis coverage, providing external status indication. Conspicuous high luminance indicators on the emitter/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 Standard (KRS) conditions for specific models (BWC80-14HD). It boasts an IP67 protection structure.
