SICK WL280-2P2431 Light Grid | Fork Type, 2-Beam, IP65, 24V DC, PNP Output

SICK WL280-2P2431 Light Grid | Fork Type, 2-Beam, IP65, 24V DC, PNP Output

SICK WL280-2P2431 light grid specifications. Fork type photoelectric sensor, 2 beams, 24V DC, PNP output, IP65, for object detection and counting.

Product Overview

The SICK WL280-2P2431 is a fork-type, 2-beam photoelectric light grid sensor designed for object detection, counting, and positioning applications. It consists of a transmitter and receiver in a single U-shaped housing, creating a precise detection window. The sensor provides two independent PNP switching outputs, one for each beam, allowing for advanced object profiling or two-point monitoring. It is rated IP65 for use in industrial environments.

Technical Specifications

Key Features

• 2 Independent Beams:​ Allows for object height differentiation, counting, or dual-point verification

• PNP Outputs:​ Two sourcing outputs, one for each beam

• Configurable Logic:​ Each output can be set as NO or NC

• High Switching Frequency:​ Up to 1 kHz per beam for fast-moving objects

• IP65 Protection:​ Resistant to dust and water jets

• M12 Connector:​ Standard industrial quick-disconnect

• Easy Alignment:​ Integrated alignment aids for simple setup

• Compact Design:​ Space-saving U-shaped profile

Applications

• Object counting on conveyors

• Small part detection and sorting

• Height verification and profiling

• Fill level control in vials or containers

• Break-in detection for safety guarding (non-safety rated)

• Packaging and assembly machine monitoring

Important Notes

1. This is a standard photoelectric sensor, not a safety-rated light curtain. Do not use for personnel safety guarding.

2. The two beams operate independently; objects can be detected by one or both beams.

3. Output logic (NO/NC) and other parameters are configurable via DIP switches or an external teach-in wire (model dependent).

4. An M12, 8-pin male connector cable must be purchased separately.

5. Performance can be affected by ambient light; ensure installation away from strong direct light sources.
