Cylindrical metal sensor with angled head and M12 connector

Sick

Sick VTF18-3P5440 photoelectric proximity sensor PNP

SKU CH-XCYW-7ZMQ4

A photoelectric proximity sensor with PNP dark-switching output and 0–45 mm range in an IP67 brass housing

  • Photoelectric proximity sensing up to 50 mm
  • Infrared LED for reliable non-contact detection
  • PNP dark-switching output for simple integration
  • M12 4-pin connector enables quick installation
  • IP67 metal housing withstands harsh environments

Sick VTF18-3P5440 PNP proximity sensor

This photoelectric proximity sensor uses infrared LED light to detect objects up to 45 mm away. It operates on a 10 V DC to 30 V DC supply with a PNP dark-switching output. The cylindrical angled housing measures 75 mm and carries an IP67 enclosure rating for harsh environments.

Suits automation needing PNP dark switching.

Engineers specifying PNP dark-switching logic for 10 V DC to 30 V DC systems will find the sensor a direct fit. The 2 ms response time supports fast detection cycles. Buyers who need AC voltage operation or a light-switching output should look at alternative sensor types.

M12 4-pin connector decides compatibility

The sensor terminates in a male M12 4-pin connector, which dictates the mating cable or junction block required for installation. Verify that the control cabinet or field-wiring harness uses the same connector style before ordering. A mismatched connector will prevent electrical connection.

Questions about this item

What supply voltage must my system provide for the VTF18-3P5440 to operate?

The sensor requires a DC supply between 10 V and 30 V with no more than 10 % ripple, drawing a maximum of 30 mA.

Will the M12 4-pin connector on this sensor mate with the M12 cables I already use on older Sick sensors?

Yes, the VTF18-3P5440 uses a standard M12 4-pin male connector, so existing M12 4-pin cables will plug straight in.

How can I confirm the sensor is detecting correctly once it is powered and wired?

With an object inside the 0–45 mm sensing range the PNP output pulls high in dark-switching mode; a multimeter or PLC input will show the voltage change.
