Cylindrical angled plastic sensor with 2 m PVC cable

Sick

Sick VTF18-3E5912 Photoelectric Proximity Sensor NPN

SKU CH-FG9P-KGX4B

Photoelectric proximity sensor detects objects up to 45 mm with NPN output and IP67 housing

  • Detects objects up to 50 mm with infrared LED
  • Adjustable sensing range via potentiometer for 45 mm operation
  • NPN light-switching output responds in 2 ms
  • IP67-rated plastic housing withstands –25 °C to +70 °C
  • 2 m PVC cable with 0.14 mm² conductors connects at 10–30 V DC

Sick VTF18-3E5912 photoelectric sensor

The Sick VTF18-3E5912 is a cylindrical photoelectric proximity sensor with an NPN switching output. It detects objects using infrared LED light across a sensing range up to 45 mm, with a maximum range of 50 mm. The angled housing measures 60.6 mm and carries an IP67 enclosure rating for dust and water resistance. It suits automation tasks that need reliable short-range presence detection.

Check supply voltage and wiring before ordering

Verify that your control system provides a DC supply between 10 V and 30 V with ripple below ten percent. The sensor draws up to 30 mA and connects via a two-metre PVC cable with 0.14 mm² conductors and a 3.1 mm outer diameter. Ensure the NPN light-switching logic matches your input module and that the potentiometer adjustment is accessible in your mounting position.

Replaces older cylindrical sensors

This unit upgrades from sensors that lack IP67 sealing or that use a larger housing unsuited to tight spaces. The jump is worthwhile when you need the 45 mm sensing range combined with a 2 ms response time and an operating temperature span from –25 °C to +70 °C. It is not for applications requiring longer sensing distances or PNP output logic.

Questions about this item

What comes in the box with the SICK VTF18-3E5912 sensor and what must I buy separately?

The sensor ships with a 2 m PVC cable permanently attached; you only need to provide a 10–30 V DC power supply and any mounting hardware such as brackets or M18 nuts.

How do I choose between the 45 mm and 50 mm sensing-range figures?

Use the 45 mm value for reliable detection of standard targets; the 50 mm figure is the absolute maximum under ideal conditions.

What does the 2 ms response time mean when the sensor is installed on a production line?

The output can switch every 2 ms, so objects moving past the beam at up to several metres per second will still be detected reliably.
