SICK VL18-4P3240 6013551 V18 Photoelectric Sensor

SICK V18 cylindrical photoelectric sensor for retro-reflective object detection at up to 3.7 m. Operates with a visible red LED, integrated polarizing filter, and adjustable sensitivity via 270° potentiometer. The compact M18 metal housing is rated IP67 for use in wet, dusty industrial environments.

Applications:

• Material handling on belt conveyors and roller tracks

• Pick‑and‑place stations for positioning, counting, and empty detector

• Door monitoring for operation and safety tasks
