Cylindrical nickel-plated brass sensor M18 thread 63.6 mm length with 2 m PVC cable

Sick

Sick VTF18-3F1212 Photoelectric Proximity Sensor PNP

SKU CH-05XE-XC0DP

Detects objects from 3 mm to 90 mm with infrared light, focused optics and PNP output in a nickel-plated brass M18 housing rated IP67

  • Photoelectric proximity sensor with background blanking for precise detection
  • PNP light-switching output handles up to 100 mA load current
  • 10–30 V DC supply voltage suits standard industrial power rails
  • IP67-rated nickel-plated brass housing resists dust and water ingress
  • 2 m PVC cable with 0.14 mm² conductors simplifies wiring

Industrial photoelectric sensor PNP

The Sick VTF18-3F1212 is a cylindrical photoelectric proximity sensor with background blanking for industrial automation. It operates on a 10 V DC to 30 V DC supply and provides a PNP light-switching output with a 100 mA maximum current. The metal housing carries an IP67 enclosure rating and weighs 120 g.

Focused infrared optics and potentiometer adjustment

A focused infrared LED produces a 3 mm light spot at a 50 mm distance, enabling precise detection of small objects. The sensing range is adjustable from 3 mm to 90 mm via a 270-degree potentiometer, while background blanking ignores objects beyond the set point. A 2 m PVC cable with three 0.14 mm² conductors simplifies wiring.

Limits of the 250 Hz switching frequency

The sensor switches at a maximum of 250 Hz with a 2 ms response time, so it cannot resolve events faster than this rate. The 10 % ripple tolerance on the supply voltage requires a stable DC source. Operating temperature spans –25 °C to +70 °C, and the M18 x 1 thread with 63.6 mm length dictates the mounting envelope.

Questions about this item

How often does the potentiometer on the VTF18-3F1212 need recalibration after installation?

The 270-degree potentiometer sets the sensing range once during setup; no scheduled recalibration is required unless the application distance changes.

What limits continuous operation of the VTF18-3F1212 — heat, duty cycle, or the 250 Hz switching frequency?

The 250 Hz switching frequency and 2 ms response time set the maximum event rate; the sensor is rated for continuous duty within the –25 °C to +70 °C ambient range.

Does the 30 mA current draw or the IP67 metal housing cause noticeable heat during all-day use?

Power consumption is 30 mA at 10–30 V DC, so self-heating is minimal; the nickel-plated brass housing and IP67 rating handle sustained operation without extra cooling.
