SICK Light Intensity Sensor Ultraviolet LED 12.5 mm, NPN, 100 mA, IP67 24V dc

SICK LUTM Series Luminescence Sensors, 12.5mm Maximum Detection, 24V Maximum Supply Voltage - LUTM-UN81162P

This luminescence sensor unit detects fluorescent emissions using an ultraviolet LED light source and is designed for integration into automated inspection and sensing setups where Compact UV detection is required. It operates in a range of industrial environments and provides a discrete electronic switching output for downstream control systems.

Features and Benefits:

• NPN output provides a simple switching Interface for controllers
  24V supply compatibility supports common industrial power rails
  Switching frequency of 6kHz enables Rapid detection cycles
  Maximum current draw of 100mA minimises power loading on circuits
  IP67 rating allows use in dusty and washdown conditions
  Cable Terminal simplifies permanent wiring into machine panels

Applications

• Suitable for industrial automation inspection of fluorescent markers
  Ideal for machine-vision pre-screening requiring UV excitation
  Used for electronics assembly checks where Compact UV sensing helps
  Can be used for mechanical systems monitoring fluorescence-driven indicators
  Used with control cabinets that require sealed sensor connections

What housing material is used and how does that affect mounting options?

The housing is MADE from ABS plastic which offers a lightweight, impact-resistant enclosure compatible with standard bracket and clamp mounting methods.

What temperature range can I expect reliable operation in?

The device functions between -10°C and 55°C so it is suitable for typical factory floor and enclosed equipment ambient conditions.

How close must a target be for reliable detection?

The maximum detection distance is 12.5mm, allowing it to sense near-field fluorescent features or markers.

How is status indicated during operation?

An integrated LED status display provides Visual confirmation of operating state and switching activity.
