The SICK WS18-3D430 photoelectric sensor is a high-precision, industrial-grade visible red light sensor, suitable for long-distance detection and precise positioning scenarios. This sensor uses a red LED light source, with a maximum detection distance of up to 20 meters. The spot diameter is Ø 450mm at 15 meters, and the beam focusing Angle is only 1.5°, ensuring stable recognition of distant targets. The sensor supports PNP output and provides complementary output functions, which can meet the control requirements of complex automation systems and is widely used in industrial automation, logistics inspection, material handling and other fields.
