Product Description

The SICK LUT9U-P120L (1046188) is a high-performance luminescence sensor from the renowned LUT9 series, designed to set new standards in industrial detection. Utilizing a powerful UV LED light source with a 375 nm wavelength, it reliably identifies fluorescent marks and substances even on challenging backgrounds such as wood, paper, or metal. The sensor features a robust zinc die-cast housing and a generous 20mm sensing range, making it ideal for high-speed automated environments.

Equipped with a simple teach-in button and IO-Link functionality, the LUT9U-P120L allows for rapid commissioning and seamless integration into Industry 4.0 architectures. Users can adjust switching thresholds and monitor performance in real-time. Its impressive switching frequency (up to 6.5 kHz) and ultra-fast response times (minimum 75 µs) ensure precise detection of marks on rapidly moving production lines. Whether used for quality control, sorting, or positioning, this sensor provides the reliability and technical sophistication required for modern manufacturing processes.

Key Performance Features

• High Switching Frequency: Adjustable settings of 0.5 kHz, 2.5 kHz, or 6.5 kHz to suit various line speeds.
• Ultra-Fast Response: Minimum response time of 75 µs for high-precision detection.
• Integrated IO-Link: Enables easy parameterization, remote monitoring, and simple sensor replacement via the control system.
• Advanced Receiving Filter: Features a KV 418 receiving filter (450 nm to 750 nm) for superior signal differentiation.
• Variable Time Delays: Integrated switch-off delay options (0 ms, 10 ms, 20 ms) for optimized signal processing.
• Bar Graph Display: Provides visual feedback on the luminescence intensity for easier alignment and monitoring.

Ideal Applications

• Packaging Industry: Detecting invisible registration marks or glue traces on packaging materials.
• Wood Processing: Identifying fluorescent chalk marks for automated cutting and sorting.
• Automotive Industry: Verification of lubricants, oils, or primers containing fluorescent tracers.
• Textile Manufacturing: Monitoring yarn presence or detecting fluorescent markings for fabric alignment.
• Pharmaceuticals: Checking for the presence of labels or leaflets marked with UV-active inks.
