Cylindrical plastic photoelectric proximity sensor with M12 connector

Sick

Sick VTE18-3P2640 Photoelectric Proximity Sensor PNP

SKU CH-XFD8-31BGQ

Photoelectric proximity sensor detects objects from 3 mm to 170 mm with infrared LED, PNP dark-switching output, 2 ms response, M12 connector, and IP67 housing

  • Detects objects up to 200 mm with infrared LED
  • 3 mm to 170 mm reliable sensing range for precision
  • PNP dark-switching output integrates with standard PLCs
  • IP67 enclosure withstands dust and water immersion
  • Operates from -25 °C to +70 °C in harsh environments

SICK VTE18-3P2640 Photoelectric Proximity Sensor PNP

This cylindrical photoelectric proximity sensor detects objects using an infrared LED with a 2.8° dispersion angle. It operates on a 10 V DC to 30 V DC supply and provides a PNP dark-switching output via a 4-pin M12 male connector. The plastic housing meets IP67 enclosure rating for dust and water protection.

Upgrade from basic limit switches or diffuse sensors

The potentiometer adjustment allows precise setting of the sensing range between 3 mm and 170 mm, with a maximum reach of 200 mm. A 2 ms response time suits fast automation cycles where mechanical switches wear out or lack repeatability. The jump is worth it when non-contact detection reduces maintenance on moving parts.

Handles clear object detection up to 170 mm

The IP67-rated plastic housing and PMMA optics withstand temperatures from –25 °C to +70 °C. It runs out of headroom beyond the 200 mm maximum range or when applications require background suppression not provided by this diffuse mode. UL file NMFT2.E175606 confirms component recognition.

Questions about this item

What mounting hole size does the 78 mm cylindrical sensor need?

The sensor has a cylindrical housing with a 78 mm dimension and uses an M12 4-pin male connector for electrical connection.

How do I set the sensing distance on the potentiometer for the 3 mm to 170 mm range?

Adjust the potentiometer on the housing while the target is at the desired distance within the 3 mm to 170 mm sensing range until the output switches.

How often should I clean the PMMA optics on this IP67 sensor?

Clean the PMMA optics whenever dust or residue builds up; the IP67 enclosure rating protects the internals during wash-down.
