SICK – VL18‑4P3640 (6013605) – M18 Retro‑Reflective Photoelectric Sensor

The SICK VL18‑4P3640 (MPN 6013605) is a reliable M18 cylindrical retro-reflective sensor from the V18 series. With a selectable light/dark PNP output and a robust plastic housing, this sensor detects objects from 0.05 m up to 3 m—and extends to 3.7 m when paired with a C110A reflector. The 4‑pin M12 connector and IP67 rating ensure durability in industrial use.
