Sick VL18-3F3812 M18 photoelectric retro-reflective sensor PNP 2 m cable

SKU CH-GCQ7-VSGE2

M18 cylindrical photoelectric retro-reflective sensor with 2 m PVC cable, PNP light-switching output, 250 Hz switching frequency and IP67 enclosure rating

  • Detects objects up to 3.7 m away with visible red LED light
  • Polarised retro-reflective sensing ignores shiny surfaces for reliable switching
  • PNP light-switching output delivers 100 mA at 250 Hz response
  • IP67-rated PBT/PC housing withstands –25 °C to +70 °C environments
  • Pre-wired 2 m PVC cable with 3-wire 0.14 mm² conductors simplifies installation

Sick VL18-3F3812 Retro-Reflective Sensor

The Sick VL18-3F3812 is a cylindrical photoelectric retro-reflective sensor built for industrial detection tasks. It operates on 10 to 30 V DC supply voltage and uses a PNP light-switching output with a 100 mA maximum load. A 2 m PVC cable provides the electrical connection.

Suits Fixed-Range Automation.

This sensor fits machines that need a set sensing window of 0.05 m to 3 m with visible red LED emission. Builders who require teach-in or potentiometer adjustment for changing target distances should look at models that offer those controls. The fixed optics and 250 Hz switching frequency support steady, repeatable detection.

M18 x 1 Thread With IP67 Housing

The M18 x 1 threaded barrel measures 60.6 mm in length and meets IP67 enclosure rating for dust and water ingress protection. This single mechanical spec determines whether the unit mounts in the available fixture and survives the operating environment.
