Sick VTE18-4N4812 Photoelectric proximity sensor NPN

SKU CH-Y73Z-MX7V5

Detects objects from 5 mm to 350 mm using infrared light with an NPN output, selectable light/dark switching, a 2 m PVC cable, and IP67 protection

  • Detects objects up to 400 mm with infrared LED
  • Cylindrical M18 housing fits standard mounting points
  • IP67 enclosure rating resists dust and water ingress
  • Operates on 10 V to 30 V DC supply voltage
  • 2 m PVC cable with four-wire connection included

Industrial proximity sensing

The Sick VTE18-4N4812 is a cylindrical photoelectric proximity sensor with an M18 x 1 thread diameter and a 60.6 mm housing length. It detects objects using infrared light across a sensing range of 5 mm to 350 mm with a maximum reach of 400 mm. The NPN switching output and selectable light or dark switching mode suit automation and control tasks in industrial environments.

Sustained operation characteristics

The sensor operates on a 10 V DC to 30 V DC supply with a ripple tolerance of 10 percent and draws 30 mA of power. It delivers a response time of 2 ms and a switching frequency of 250 Hz for consistent detection cycles. An IP67 enclosure rating and an ambient operating temperature span of –25 °C to +70 °C support reliable performance under continuous load.

Upgrade and replacement context

The 2 m PVC cable with a 0.14 mm² conductor cross-section replaces older hard-wired sensors that lack radial optical axis alignment or adjustable switching modes. The jump is worthwhile when an application requires a plastic PBT/PC housing with PMMA optics and UL file number NMFT2.E175606 compliance. It does not serve buyers who need a longer cable run or a different output logic type.

Questions about this item

How much power does the VTE18-4N4812 draw when operating continuously on a 30 V DC supply?

The sensor consumes 30 mA at the supply voltage, which ranges from 10 V DC to 30 V DC, so continuous operation at the upper limit still draws only 30 mA.

What supply voltage and output wiring must the installer provide for the NPN switching output to function?

The unit requires a 10 V DC to 30 V DC source with less than 10 % ripple and a four-wire cable connection; the NPN output sinks up to 100 mA and is selectable between light and dark switching via the L/D control wire.

Will the sensor's M18 x 1 thread and 60.6 mm cylindrical body fit the same mounting holes as older M18 photoelectric sensors?

Yes, the housing uses the standard M18 x 1 thread and a 60.6 mm length, so it matches the mechanical footprint of legacy M18 cylindrical sensors.
