Cylindrical plastic photoelectric sensor with 2 m PVC cable and potentiometer adjustment

Sick

Sick VTF18-3F5912 Photoelectric proximity sensor PNP

SKU CH-A797-FR408

A photoelectric proximity sensor with PNP output detects objects up to 45 mm using infrared LED light

  • PNP output simplifies wiring to positive logic
  • 45 mm sensing range detects objects at short distance
  • 10–30 V DC supply fits common industrial rails
  • IP67 enclosure resists dust and water ingress
  • 2 ms response time enables fast switching cycles

Industrial proximity sensor for 10–30 V DC systems

The Sick VTF18-3F5912 is a cylindrical photoelectric proximity sensor with a PNP switching output. It operates on a 10 V DC to 30 V DC supply and draws a maximum of 30 mA. The infrared LED detects objects at ranges up to 50 mm and switches in light mode with a 2 ms response time. A built-in potentiometer allows range adjustment for precise positioning.

Sensing capped at 50 mm with 2 ms switching

The sensor’s maximum sensing range reaches 50 mm, though the rated operating range is 0 mm to 45 mm. Infrared light from the LED provides detection within this window. The 2 ms response time sets the fastest reliable switching speed for automated sequences. A 2 m PVC cable with 0.14 mm² conductors carries power and signal without a plug connector.

Verify 10–30 V DC supply and IP67 mounting

Confirm that your control circuit supplies 10 V DC to 30 V DC with ripple below 10 % and can sink the sensor’s PNP output. The IP67-rated plastic housing tolerates ambient temperatures from –25 °C to +70 °C. Ensure the 60.6 mm cylindrical form factor and 3.1 mm cable diameter fit the available mounting space and cable routing.

Questions about this item

Which sensing range version should I choose for my application?

The sensor offers a maximum sensing range of 0 mm to 50 mm and a standard sensing range of 0 mm to 45 mm, so select based on the maximum distance you need to detect objects reliably.

What does the 2 ms response time mean once the sensor is installed?

The sensor reacts to a change in light reception within 2 milliseconds, allowing it to detect fast-moving objects or rapid process changes on a production line.

What does the 10 V DC to 30 V DC supply voltage cap in practice?

The sensor operates reliably on any DC supply between 10 V and 30 V with a maximum 10 % ripple, drawing no more than 30 mA, so it fits standard industrial control voltages.
