Cylindrical nickel-plated brass sensor, M18 thread, 75 mm long, radial M12 connector, IP67

Sick

Sick VTF18-3F5440 photoelectric proximity sensor PNP

SKU CH-2KE0-S5R4E

Photoelectric proximity sensor with background blanking detects objects up to 45 mm using focused infrared optics in a nickel-plated brass M18 housing rated IP67

  • PNP output simplifies wiring to positive-logic controllers
  • 0–45 mm sensing range covers short-distance detection
  • M12 4-pin connector enables quick installation
  • IP67 rating withstands dust and water jets
  • 25 °C to +70 °C operating temperature suits harsh environments

Industrial photoelectric sensor for short-range

The Sick VTF18-3F5440 is a cylindrical photoelectric proximity sensor with background blanking and a radial optical axis. It operates on 10 V DC to 30 V DC supply voltage and provides a PNP light-switching output rated at 100 mA maximum current. The focused optics produce a 3 mm light spot at 25 mm distance using an infrared LED source.

Suited for automation tasks needing precise 45 mm

This unit fits applications where a metal M18 threaded housing and IP67 enclosure rating are required for harsh environments. The 250 Hz switching frequency and 2 ms response time support fast cycle times. Buyers who need longer sensing ranges beyond 50 mm or NPN output logic should look at alternative sensor models.

Straightforward M12 connector mounting

Installation uses a standard 4-pin M12 male connector for quick wiring. The sensing range is set via a 270° potentiometer on the housing. The nickel-plated brass body weighs 120 g and tolerates ambient temperatures from –25 °C to +70 °C. Ensure the supply ripple stays within 10 % to avoid output instability.

Questions about this item

What power supply voltage range must my system provide for the VTF18-3F5440 sensor to operate?

The sensor requires a supply voltage between 10 V DC and 30 V DC with a maximum ripple of 10 % to function correctly.

Will the M12 4-pin connector on this sensor mate with the existing M12 cables in my M18 mounting setup?

Yes, the sensor uses a standard male M12 4-pin connector, which is compatible with common M12 4-pin cables used for M18 cylindrical sensors.

How can I verify the sensor is detecting objects at the intended distance after installation?

Adjust the 270° potentiometer while monitoring the PNP output; the LED indicator will show switching status when an object enters the 0 mm to 45 mm sensing range.
