Telemecanique Sensors XUK1ARCNL2 Retroreflective Photoelectric Sensor

SKU CH-N3QJ-X2SD2

Retroreflective photoelectric sensor with selectable light-on or dark-on operating mode

  • TypeIndustrial Electrical Controls & Automation
  • Selectable light/dark operation suits varied detection tasks
  • Retroreflective sensing detects objects without separate receiver
  • Telemecanique Sensors brand ensures industrial-grade reliability
  • New condition guarantees full factory performance
  • Ships bare for direct integration into existing systems

Product Identity

The Telemecanique Sensors XUK1ARCNL2 is a retroreflective photoelectric sensor designed for industrial electrical controls and automation. It suits engineers and technicians who need reliable object detection in conveyor, packaging or material-handling systems.

Operating Modes

The sensor offers selectable light-on or dark-on output logic, allowing the installer to match the switching behaviour to the application without extra wiring. Power consumption and thermal load remain low during continuous operation in standard industrial environments.

Installation Fit

The bare unit mounts directly onto machinery frames or DIN-rail adapters using standard fixing centres. Its compact housing leaves panel space free for additional modules, while the retroreflective principle eliminates the need for a separate receiver housing and cable run.

Questions about this item

How do I install the XUK1ARCNL2 sensor and which wiring step is most often missed?

Mount the sensor on a stable surface using the integral bracket, connect the three-wire DC cable to the supply matching the sensor's voltage rating, and select light-on or dark-on mode via the switch; the step most often missed is verifying the reflector is perpendicular to the beam axis before tightening the sensor.

What maintenance or replacement will the XUK1ARCNL2 retroreflective photoelectric sensor need over time?

Clean the sensor lens and the retroreflector regularly with a soft, lint-free cloth to remove dust or oil; replace the reflector if its reflective surface becomes scratched, yellowed or cracked, and replace the sensor itself if the output no longer switches reliably after cleaning.

What is the first performance limit that appears when the XUK1ARCNL2 runs continuously in a dusty environment?

Dust accumulation on the lens and reflector attenuates the infrared beam, reducing the excess gain until the sensor can no longer reliably detect the reflected signal, causing missed detections or false triggers.
