SICK LUT3-650 Luminescence Sensor

The SICK LUT3-650 luminescence sensor is a compact UV‑illuminated detector designed to sense luminescent signals at distances up to 50 mm, with a stated working range of 30–60 mm and a 375 nm UV light source for reliable excitation of luminescent materials. It operates from 12 to 30 V DC, featuring a low‑noise supply and a long service life of about 100,000 hours at 25 °C, making it suitable for continuous industrial use. The housing measures 30.4 mm wide by 53 mm high by 80 mm deep, with the light emitted on the long side and a 5 × 15 mm light spot directed vertically toward the target; the receiving optics include a filter system that blocks shorter wavelengths and accepts signals in the 450–750 nm band, with receiving filters limited to ≤420 nm. The LUT3‑650 provides a light‑switching output and uses a 4‑pin M12 connector for straightforward integration into automation networks. Its part number is 1015398, placing it in SICK’s LUT3 luminescence sensor family for repeatable detection of luminescent features in industrial environments.
