VL18L-4P324 Retro-reflective Laser Sensor 35m PNP Class 1 | SICK

The Original New SICK VL18L-4P324 (6027430) is a cylindrical photoelectric retro-reflective sensor from the V18 Laser series, engineered for long-range object detection with a visible red laser light source. Its M18 × 1 threaded metal housing with axial optical axis enables straightforward integration into standard mounting configurations. The sensor provides a PNP output with light/dark switching selectable via control input C, and sensitivity can be adjusted either electronically or via the single teach-in button. Rated IP67, it is designed for reliable operation in demanding industrial environments, with a maximum sensing range of 35 m (30 m rated) when paired with the P250F reflector.

Core Engineering Highlights:
