Cylindrical angled plastic sensor with M12 connector

Sick

Sick VTE18-3N4940 photoelectric proximity sensor NPN

SKU CH-QANH-7WA87

Photoelectric proximity sensor detects objects up to 170 mm with infrared LED, NPN dark-switching output, M12 connector and IP67 housing

  • NPN dark-switching output suits common PLC inputs
  • Infrared LED with 2.8° dispersion for precise detection
  • Sensing range adjustable from 5 mm to 350 mm
  • IP67-rated plastic housing withstands harsh environments
  • Operates on 10–30 V DC with 2 ms response time

Industrial detection sensor

The Sick VTE18-3N4940 is a cylindrical photoelectric proximity sensor designed for automated industrial detection tasks. Its NPN dark-switching output and M12 connector suit PLC input modules in packaging, material-handling and assembly equipment.

Sustained operation profile

The sensor draws a maximum of 30 mA from a 10 V DC to 30 V DC supply with 10 % ripple tolerance. An IP67 enclosure and an operating range of –25 °C to +70 °C allow continuous duty in wash-down zones and unheated factories without thermal derating.

Decisive sensing range

The adjustable potentiometer sets a usable detection window from 5 mm to 350 mm using an infrared LED with a 2.8° dispersion angle. Applications requiring longer range or a different output logic will need another device.

Questions about this item

How much power does the VTE18-3N4940 sensor draw during continuous operation?

The sensor consumes a maximum of 30 mA from a 10 V DC to 30 V DC supply with ripple up to 10 %.

Which connector and voltage supply must already be available to install this sensor?

A male M12 4-pin connector and a 10 V DC to 30 V DC power source are required for connection.

Will the IP67-rated housing survive the same temperature range as my existing IP67 equipment?

Yes, the sensor operates from –25 °C to +70 °C, matching the typical industrial IP67 temperature specification.
