Cylindrical metal sensor with angled head and 2 m PVC cable

Sick

Sick VS/VE18-3P3412 Through-beam Photoelectric Sensor PNP

SKU CH-7GEP-DN847

A through-beam photoelectric sensor with PNP dark-switching output, 20 m maximum range, and IP67-rated metal housing

  • Detects objects up to 20 m away with through-beam infrared sensing
  • PNP dark-switching output reacts in 2 ms for fast automation response
  • IP67-rated brass and plastic housing withstands –25 °C to +70 °C environments
  • 10–30 V DC supply with 30 mA draw suits standard industrial power rails
  • 2 m PVC cable with 0.14 mm² conductors simplifies panel wiring

Through-beam sensor for industrial detection

The Sick VS/VE18-3P3412 is a through-beam photoelectric sensor designed for presence detection in automation and control systems. It operates on a 10 V DC to 30 V DC supply and provides a PNP dark-switching output suitable for standard PLC inputs. The unit suits engineers who need reliable non-contact sensing over distance.

Brass housing with IP67 rating and fixed cable

The cylindrical angled housing uses nickel-plated brass and plastic with PMMA optics, rated IP67 for dust and water protection. A 2 m PVC cable with 0.14 mm² conductors and 3.1 mm diameter exits the sensor for direct wiring. Operating temperature spans –25 °C to +70 °C for harsh environments.

Potentiometer adjustment and 20 m maximum range

A built-in potentiometer allows sensitivity adjustment for the infrared LED beam. Maximum sensing range reaches 20 m with a practical range of 14 m and a 2 ms response time. The sensor includes UL file NMFT2.E175606 compliance for electrical safety standards.

Questions about this item

What sensing range does the through-beam sensor achieve in practice?

The sensor detects objects up to 14 m away in standard operation, with a maximum range of 20 m under ideal conditions.

What are the physical dimensions and mounting requirements for the cylindrical housing?

The angled cylindrical housing measures 60.6 mm and uses a metal brass nickel-plated body with plastic components for mounting.

How is the 2 m PVC cable connected and what wiring mistake should be avoided?

The cable has a 0.14 mm² conductor cross-section and 3.1 mm diameter; ensure the 10–30 V DC supply matches the PNP dark-switching output polarity.
