Cylindrical metal photoelectric sensor with angled head and 2 m cable

Sick

Sick VTF18-3P1312 Photoelectric Proximity Sensor PNP

SKU CH-3627-7VZBY

Photoelectric proximity sensor detects objects up to 90 mm with PNP dark-switching output and IP67-rated metal housing

  • Detects objects up to 90 mm with infrared LED
  • PNP dark-switching output signals presence reliably
  • 2 ms response time suits fast automation cycles
  • Brass nickel-plated metal housing rated IP67 resists harsh environments
  • 10–30 V DC supply with 2 m PVC cable simplifies wiring

Sick VTF18-3P1312 Photoelectric Sensor

The Sick VTF18-3P1312 is a cylindrical photoelectric proximity sensor with a PNP dark-switching output. It detects objects using infrared LED light across a sensing range of 3 mm to 90 mm. The brass nickel-plated metal housing carries an IP67 enclosure rating for dust and water protection. It suits automation engineers and maintenance technicians who need reliable short-range presence detection.

Upgrading From Basic Limit Switches

This sensor replaces mechanical limit switches that wear out or fail in dirty environments. The jump is worth it when you need non-contact detection with a 2 ms response time and no moving parts to maintain. It is not for applications requiring sensing distances beyond 100 mm or analogue output signals for distance measurement.

Simple Cable Installation

Installation uses a pre-wired 2 m PVC cable with 0.14 mm² conductors and a 3.1 mm outer diameter. The potentiometer allows straightforward range adjustment without software tools. Common issues include exceeding the 10 V DC to 30 V DC supply limits or mounting the angled head where debris blocks the PMMA optics.

Questions about this item

What mounting diameter does the 63.6 mm cylindrical brass housing need?

The sensor uses an M18 thread so a standard 18 mm clearance hole fits the nickel-plated brass barrel.

Which wire carries the PNP output on the 2 m PVC cable?

The black conductor (0.14 mm²) is the switching output; connect it to the load and the blue wire to 0 V.

When should the potentiometer be re-adjusted after installation?

Re-adjust if the sensing face gets scratched, coated with oil, or if ambient temperature shifts beyond –25 °C to +70 °C.
