SICK VTE18-3F8912 Photoelectric proximity sensor PNP

SKU CH-B8FS-9BX3A

Detects objects from 10 mm to 700 mm using an infrared LED with a 2.8° beam angle, adjustable via a 270° potentiometer, and outputs a PNP light-switching signal at up to 250 Hz through a 2 m PVC

  • Reliable detection up to 700 mm with infrared LED
  • Adjustable sensing range via 270° potentiometer for precise setup
  • Fast 250 Hz switching frequency suits high-speed processes
  • IP67 enclosure rating protects against dust and water ingress
  • Operates from –25 °C to +70 °C in harsh environments

Industrial Proximity Sensing

The SICK VTE18-3F8912 is a cylindrical photoelectric proximity sensor designed for automated detection tasks. It operates on a 10 V DC to 30 V DC supply with a PNP light-switching output. The M18 x 1 threaded housing measures 60.6 mm in length and weighs 100 g. An IP67 enclosure rating suits industrial environments.

Sustained Load Behaviour

A 250 Hz switching frequency and 2 ms response time maintain consistent detection during continuous operation. Power consumption stays at 30 mA with ripple limited to 10 %. Circuit protection covers supply polarity, short-circuit, overload and false-pulse suppression. The ambient operating range spans –25 °C to +70 °C without performance loss.

Practical Interface Limits

The 2 m PVC cable with 0.14 mm² conductors and 3.1 mm diameter fixes the installation reach. Sensing range extends from 10 mm to 700 mm, with a maximum of 800 mm producing a 40 mm light spot at 2.8° dispersion. Potentiometer adjustment covers 270° for range setting. Plastic PBT/PC housing and PMMA optics limit chemical exposure.

Questions about this item

How much heat does the VTE18-3F8912 generate when running continuously on a 30 V DC supply?

Power consumption is 30 mA at up to 30 V DC, so heat output stays low during all-day operation.

What voltage supply and output interface must the installer provide for this PNP sensor?

The sensor requires 10 V DC to 30 V DC and delivers a PNP light-switching output with a maximum load of 100 mA.

Will the M18 x 1 threaded housing and 2 m PVC cable fit the brackets and cable glands I already use for older M18 sensors?

Yes, the housing uses an M18 x 1 thread and a 3.1 mm diameter PVC cable, matching common M18 mounting and gland sizes.
