Sick VTE18-3P8840 Photoelectric Proximity Sensor PNP

SKU CH-NQQP-15S25

Photoelectric proximity sensor detects objects from 10 mm to 700 mm with infrared LED, PNP dark-switching output, and IP67-rated plastic housing

  • Detects objects up to 800 mm with infrared LED
  • Sensing range adjustable from 10 mm to 700 mm via potentiometer
  • Fast 2 ms response time suits high-speed lines
  • IP67 enclosure resists dust and water ingress
  • Operates reliably from –25 °C to +70 °C

Sick VTE18-3P8840 Photoelectric Sensor

The Sick VTE18-3P8840 is a cylindrical photoelectric proximity sensor designed for industrial automation and position sensing tasks. It detects objects using an infrared LED with a 2.8° dispersion angle across a range of 10 mm to 700 mm. The plastic housing carries an IP67 enclosure rating and operates on a 10 V DC to 30 V DC supply with a PNP dark-switching output.

Suited for discrete object detection on conveyors

This sensor suits engineers who need a compact M12-connector device with potentiometer adjustment for teach-in sensing distances up to 800 mm maximum. It is not for applications requiring background suppression, analogue distance output, or a metal housing for high-impact environments. Buyers needing a longer sensing range or a different switching logic should look at alternative sensor families.

10 V DC to 30 V DC supply

The single specification that decides fit is the PNP dark-switching output combined with the 10 V DC to 30 V DC supply voltage. Your controller must accept a PNP signal that goes high when the beam is broken, and your power rail must stay within the stated limits. The 2 ms response time and M12 4-pin connector complete the electrical interface.

Questions about this item

How do I mount and wire the cylindrical angled sensor with the M12 4-pin connector?

Mount the 75 mm plastic housing using the cylindrical angled profile and connect the 10–30 V DC supply to the M12 4-pin male connector; the potentiometer adjusts the sensing range between 10 mm and 700 mm.

What maintenance will the IP67 rated photoelectric sensor need over time?

The IP67 plastic housing and PMMA optics resist dust and water; periodically clean the lens with a soft cloth and verify the potentiometer setting after vibration or temperature cycles between –25 °C and +70 °C.

At what distance does the infrared LED beam divergence limit reliable detection?

The 2.8° angle of dispersion narrows the beam; the sensor specifies a maximum sensing range of 800 mm, but the usable range is 10 mm to 700 mm under normal conditions.
