Cylindrical angled metal sensor with 2 m PVC cable

Sick

Sick VL18-3F3312 Photoelectric retro-reflective sensor PNP

SKU CH-3PVA-P86GD

A cylindrical photoelectric retro-reflective sensor with a 0.05 m to 3.7 m sensing range, visible red LED light, PNP output, 10 V DC to 30 V DC supply, and IP67-rated metal housing

  • Detects objects up to 3.7 m with visible red LED
  • Adjustable sensing via potentiometer for precise setup
  • PNP light-switching output integrates with standard controls
  • IP67-rated metal housing withstands dust and water jets
  • Operates reliably from –25 °C to +70 °C

Industrial photoelectric retro-reflective sensor

The Sick VL18-3F3312 is a cylindrical, angled photoelectric retro-reflective sensor with PNP switching output. It operates on 10 V DC to 30 V DC supply voltage and draws up to 30 mA. The visible red LED light source provides a 2.8° angle of dispersion. A 2 m PVC cable with 0.14 mm² conductors terminates the connection.

Replaces older retro-reflective units

This model extends the sensing range to a maximum of 3.7 m and a practical range of 3 m, a clear step up from sensors capped at shorter distances. The IP67 enclosure rating and metal, brass nickel-plated housing with PMMA optics withstand –25 °C to +70 °C operating temperatures. The jump is worth it when an application demands longer reach and rugged sealing in a single package.

Check supply voltage and mounting before ordering

Verify that your control system provides 10 V DC to 30 V DC with ripple below 10 % and can accept a PNP light-switching output with a 2 ms response time. Confirm the 60.6 mm housing fits the available space and that the 2 m cable length reaches your termination point. The potentiometer adjustment requires physical access after installation.

Questions about this item

What thread size and clearance does the VL18-3F3312 sensor need for mounting?

The cylindrical housing is 18 mm in diameter and 60.6 mm long, so an M18 threaded hole with enough depth for the body and cable bend radius is required.

How do I wire the 2 m PVC cable and set the switching distance correctly?

Connect the three PNP wires to a 10–30 V DC supply, then turn the potentiometer while the reflector is at the desired distance until the output toggles cleanly.

When should I replace the cable or clean the PMMA optics on this IP67 sensor?

Inspect the Ø 3.1 mm PVC cable for cracks after repeated flexing and wipe the plastic lens whenever dust or oil reduces the 3.7 m maximum range.
