OVERVIEW

The SICK WL12-3N2431 is a retroreflective photoelectric sensor designed for reliable detection of objects across a broad range of industrial applications. Retroreflective sensors operate by emitting a beam of light towards a reflector, and the sensor detects objects when they interrupt this beam.

SPECIFICATION

• Retroreflective Operation:
  • This sensor operates on a retroreflective principle, meaning it uses a reflector to return the emitted light beam. The sensor detects objects when they block or reflect the light back differently.
  • It simplifies installation as there is no need for separate emitter and receiver units—both are contained in one housing.
• Sensing Range:
  • The sensor has a long detection range, with a maximum of 10 meters depending on the reflector and object surface.
  • It is capable of reliably detecting objects at long distances, which is useful in wide conveyor systems or large machine setups.
• PNP Output:
  • The PNP output configuration allows the sensor to provide a positive output when an object is detected, making it compatible with most industrial control systems.
• Visible Red Light:
  • The sensor uses visible red light for detection, which makes alignment and setup easier, as the red beam is easy to spot during installation and maintenance.

FEATURES

• Conveyor Systems: Used for object detection, package counting, or presence sensing on conveyor belts in packaging, logistics, and manufacturing lines.
• Transparent Object Detection: Thanks to its polarizing filter, it is suitable for detecting transparent or glossy objects, making it useful in industries like bottling or pharmaceuticals.
• Material Handling: Can be applied in material handling systems for detecting products or parts.
• Automated Machines: Ideal for various automated machines requiring accurate object detection and fast response times.
• Packaging and Labeling: Used in systems that require precise object presence detection for labeling or packaging.
