Product Description

The SICK LUTM-UN81162P (1067296) is a high-performance, intelligent luminescence sensor designed to detect fluorescent marks with exceptional reliability. Housed in a space-saving miniature casing (12 mm x 31.5 mm x 21 mm), it is specifically engineered for integration into machinery where mounting space is severely restricted. The sensor operates by emitting modulated UV light at a wavelength of 370 nm, which excites fluorescent substances to emit visible light (450 nm to 750 nm) that the sensor then evaluates.

Equipped with a fast 6 kHz switching frequency and a response time of 80 µs, the LUTM ensures high-speed processing in demanding industrial environments. It features a user-friendly 2-point teach-in method (static and dynamic) via a manual button or external cable, allowing for quick setup even with low-level luminescence or glossy backgrounds. Its NPN switching output and IP67 enclosure rating make it a durable and versatile solution for modern automated production lines requiring precise detection of invisible or visible fluorescent indicators on various packaging materials.

Key Performance Features

• Miniature Housing: Ultra-compact design allows for installation in extremely confined spaces where standard sensors cannot fit.
• High Switching Frequency: Operates at 6 kHz with an 80 µs response time, enabling accurate detection on high-speed conveyor lines.
• Versatile Teach-in: Supports both 2-point static and dynamic teach-in modes for flexible configuration based on the application.
• Superior Detection: Reliably identifies marks even with a low luminescence factor or on highly reflective/glossy surfaces.
• Rugged Construction: IP67-rated housing ensures protection against dust and water, suitable for harsh industrial conditions.
• UV LED Technology: Long service life (100,000 hours) ensures low maintenance and consistent performance over time.

Ideal Applications

• Packaging Industry: Detecting invisible marks for cutting, folding, or sorting processes on high-speed lines.
• Quality Control: Verifying the presence of fluorescent adhesives, lubricants, or security labels on products.
• Wood and Timber: Identifying fluorescent chalk marks for automated grading and sorting in sawmills.
• Logistics & Sorting: Tracking packages and parcels marked with UV-sensitive ink or labels.
• Textiles: Detection of fluorescent threads or markings during fabric processing and quality inspection.
