SICK WL280-2R4331 Photoelectric sensor
SICK WL280-2R4331 photoelectric sensor with double-lens optics, part 6044760. Precise long-distance object detection for conveyors and intralogistics.
Overview
The SICK WL280-2R4331 (part number 6044760) is a photoelectric sensor with double-lens optics for long-range object detection. The dual-lens arrangement produces a precise, concentrated light beam, which supports stable detection at longer distances and reduces false switching from adjacent surfaces.
How It Works
The sensor evaluates the returned light after it has traveled to the target or reflector and back. The double-lens optics focus the emitted beam and the received light, increasing optical contrast. When the received signal crosses the switching threshold, the output changes state.
Key Features
- Double-lens optics for a precise, well-defined light beam
- Designed for longer-distance object detection tasks
- LED light source with long service life
- Rugged rectangular housing for industrial environments
- PNP switching output (R-family order code)
- Stable switching behavior under variable ambient light
Typical Applications
- Detection of vehicles and trolleys on longer transfer sections
- Pallet presence monitoring on wide conveyor lines
- Object detection at material flow junctions
- Passage monitoring in warehouse entrances
- Long-distance presence checks in process logistics

Installation and Setup Notes
Align the optical axis carefully; the concentrated beam rewards accurate installation with stable long-term switching. Where a reflector is used, fix it rigidly and keep the optical path free of moving cables or brackets. For dark targets at long distance, verify the switching margin with the real object before commissioning.
Frequently Asked Questions
What advantage do double lenses provide?
They focus the emitted and received light, which improves optical contrast and supports precise detection at longer distances.
Is this sensor suitable for outdoor use?
It is built for industrial environments; for outdoor installation, protect it from direct weather exposure and strong sunlight.
Can it detect dark objects?
Yes, within the working range; dark objects reduce the effective distance, so the margin should be verified with the actual target.
