SICK Background Suppression Photoelectric Sensor, Barrel Sensor, 3 mm → 100 mm, PNP, IP67

SICK V18 Series Photoelectric Sensor, IP67, 2ms Response Time - VTF18-4P1240

This photoelectric sensor detects objects using infrared background suppression and is designed for industrial automation environments. Packaged in a cylindrical metal housing with corrosion-resistant nickel plating, it is intended for in-line mounting and continuous operation within typical factory temperature ranges. The device connects via a 4-pin M12 Terminal and provides a PNP switching output for control-system integration.

Features & Benefits

• 2ms response time for fast object detection and cycle support
  IP67 ingress rating for protection against dust and water
  30V maximum DC supply enabling safe low-voltage system use
  100mA maximum current for straightforward load interfacing
  Threaded mount for secure panel or bracket installation
  Operates between -25 and 70°C for varied environmental tolerance

**Applications**

• Suitable for conveyor presence sensing in packaging lines
  Ideal for detecting parts on pick-and-place equipment
  Used for position verification on automated assembly jigs
  Can be used for bin-level sensing where background suppression is needed

How is the sensor physically connected to control equipment?

Connection is via a 4-pin M12 Terminal that mates with standard industrial cabling for signal and supply lines.

Which output behaviour should I expect when integrating with PLC inputs?

The switching output follows a PNP configuration, sourcing current to the input when the sensing condition is met.

What materials provide the enclosure's mechanical protection?

The body is constructed from metal with a nickel-plated brass finish to resist wear and corrosion in industrial settings.

Are there certifications or approvals relevant to deployment in commercial systems?

It carries multiple regional and safety approvals applicable to industrial installations across EU and UK jurisdictions and recognised testing bodies.
