SICK WL12L-2B530 1018252 Laser Retro‑reflective Photoelectric Sensor 18m

SICK WL12L‑2B530 is a Class 2 laser retro‑reflective photoelectric sensor for non‑contact object detection. Visible red light (650 nm) with Ø 0.8 mm spot at 300 mm. Autocollimation optical system with integrated polarising filter allows operation without a minimum distance to the reflector in demanding industrial applications. Focusable sensing range from 300 mm to infinity. Rugged zinc die‑cast metal housing.

Applications:

• Detecting small objects (e.g., electronic components, miniature parts)

• High‑speed object detection on conveyor and sorting systems

• Material handling and positioning in logistics automation

• Packaging machinery for container and product registration

• Reliable detection of reflective surfaces (metal, shiny plastics)
