Product Description

The SICK LUT8U-11101 (Part No. 1046711) is a high-precision luminescence sensor from the LUT8 product family, designed for universal industrial use. Utilizing a powerful UV LED light source with a 375 nm wavelength, it detects fluorescent marks even on challenging surfaces such as wood, paper, or metal. The sensor features a 10 mm sensing distance and a vertical 2 mm x 6 mm light spot, ensuring reliable detection of small marks at high speeds.

Equipped with a manual 8-position rotary switch, the LUT8U-11101 allows for easy sensitivity adjustment and provides a bar graph display for real-time monitoring of the luminescence intensity. Its rugged zinc die-cast housing and IP67 rating make it suitable for harsh environments. With a rapid switching frequency of 2.5 kHz and dual PNP/NPN outputs, this sensor delivers exceptional performance and flexibility for automated production lines requiring precise object positioning or mark detection.

Key Performance Features

• High Sensitivity: Detects faint luminescence levels across a wide receiving range (450 nm to 750 nm).
• Fast Response: A switching frequency of 2.5 kHz and 200 µs response time enable use in high-speed machinery.
• Optical Filtering: Integrated KV 418 receiving filter suppresses background luminescence for error-free operation.
• User-Friendly Interface: Manual rotary switch for sensitivity adjustment complemented by a clear LED bar graph display.
• Analog Output: Includes a 0 mA … 13 mA analog output for continuous luminescence monitoring.
• Durability: Rated IP67 for protection against dust and water, housed in a heavy-duty metal casing.

Ideal Applications

• Packaging Industry: Detecting invisible marks for cutting, folding, or positioning processes.
• Wood and Timber: Identification of chalk marks or knots treated with fluorescent chemicals for sorting.
• Logistics & Sorting: Tracking items through the supply chain using UV-coded labels.
• Automotive: Verifying the presence of lubricants, adhesives, or sealants containing fluorescent tracers.
• Textile Industry: Detecting fluorescent yarn or marks for quality control and process automation.
