Cylindrical M18 photoelectric sensor with 2 m PVC cable

Sick

Sick VTE18-3N4612 photoelectric proximity sensor NPN

SKU CH-WWM8-H3M18

Photoelectric proximity sensor detects objects up to 350 mm with NPN dark-switching output, IP67-rated cylindrical M18 housing, and 2 m PVC cable

  • NPN dark-switching output simplifies PLC wiring
  • 10 – 30 V DC supply fits standard industrial power rails
  • IP67 enclosure rating resists dust and water ingress
  • 5 – 350 mm sensing range covers close and mid-range detection
  • 2 m PVC cable with 3-wire design enables direct installation

Industrial photoelectric sensor

The Sick VTE18-3N4612 is a cylindrical photoelectric proximity sensor that uses energetic infrared detection for presence sensing in automation and machine-building environments. It delivers an NPN dark-switching output on a three-wire cable, suited for PLC inputs and simple control circuits. The M18 x 1 threaded housing allows direct mounting into standard sensor brackets or tapped plates without extra adapters.

Sensing range and supply limits

Reliable detection spans 5 mm to 350 mm with a maximum reach of 400 mm, producing a 20 mm light spot at that distance and a dispersion angle of approximately 2.8°. Operation requires a 10 V DC to 30 V DC supply with ripple below 10 %, drawing up to 30 mA and switching loads up to 100 mA at 250 Hz with a 2 ms response time.

Cable, housing and sealing

A 2 m PVC cable with 0.14 mm² conductors and 3.1 mm outer diameter provides the fixed connection, eliminating separate connector purchases but preventing quick-disconnect swaps. The PBT/PC plastic housing and PMMA optics meet IP67 enclosure rating for dust and temporary immersion, while the protection class III rating suits low-voltage control circuits. Operating temperature covers –25 °C to +70 °C for unheated indoor or sheltered outdoor use.

Questions about this item

Should I choose the 350 mm or 400 mm sensing range version of the VTE18-3N4612?

The sensor has a maximum sensing range of 5 mm to 400 mm and a standard sensing range of 5 mm to 350 mm; both figures describe the same model, so no separate version choice is required.

What does the 250 Hz switching frequency mean when the sensor is installed?

It allows the NPN output to change state up to 250 times per second, with a 2 ms response time, suitable for detecting objects on fast conveyors or indexing stations.

How does the 10 V to 30 V DC supply range limit the cable length I can run?

The sensor draws up to 30 mA; voltage drop over the 0.14 mm² PVC cable must keep the supply above 10 V at the sensor, so keep cable runs short enough to stay within that limit.
