SICK LUT3 Series Luminescence Sensors, 20mm Maximum Detection, IP67 - LUT3-620


This luminescence sensor device detects fluorescent markers and materials using ultraviolet illumination for industrial automation and inspection tasks. It is intended for integration where non-contact detection of luminescent signals is required, providing signal output suitable for control systems via a standard connector.

Features and Benefits:


• Ultraviolet LED light source enables fluorescence detection up to 20mm range
• Zinc die-cast housing delivers robust protection in harsh environments
• IP67 rating allows temporary immersion and dust-tight operation
• NPN and PNP outputs permit direct interfacing with varied control logic
• 1.5 kHz switching frequency supports moderate-speed detection cycles
• M12 connector simplifies wiring and replacement in machine assemblies

Applications


• Suitable for conveyor-based fluorescent label inspection
• Ideal for component presence checks using luminescent markers
• Used for quality control in electronics assembly lines
• Can be used for sorting materials that fluoresce under UV
• Used with automated systems requiring Compact sensor heads

What supply constraints should I observe when wiring this unit?


Operate the device from a DC supply not exceeding 30V and ensure available output current does not surpass 100 mA per channel.

How does ambient temperature affect operation?


The sensor is specified to function between -10 °C and 55 °C

install it where temperatures remain within that range to maintain detection stability.

What indicators are available for diagnostics during commissioning?


An on-board LED status display provides Visual confirmation of detection states and helps with alignment during setup.
