Sick

Sick VTE18-3N2940 Photoelectric Proximity Sensor NPN

SKU CH-XGKB-GPTA0

Detects objects up to 200 mm with an infrared LED, adjustable via potentiometer, in an IP67 cylindrical housing

  • Detects objects up to 200 mm with infrared LED
  • Adjustable sensing range from 3 mm to 170 mm via potentiometer
  • Fast 2 ms response time suits high-speed automation
  • IP67-rated plastic housing withstands dust and water ingress
  • Operates on 10–30 V DC with NPN dark-switching output

Industrial proximity sensor

The Sick VTE18-3N2940 is a cylindrical photoelectric proximity sensor designed for automated detection tasks in industrial environments. It operates on a 10 V DC to 30 V DC supply and provides an NPN dark-switching output through a male M12 4-pin connector. The IP67-rated plastic housing withstands ambient temperatures from –25 °C to +70 °C.

Sensing range and response limits

The sensor detects objects from 3 mm up to a maximum of 200 mm, with a specified sensing range of 3 mm to 170 mm using infrared LED light at a 2.8° dispersion angle. A potentiometer allows sensitivity adjustment, while the response time is 2 ms. Ripple must not exceed 10 % and power consumption is 30 mA, constraining the usable power budget.

Upgrade from basic limit switches

This unit replaces mechanical limit switches or lower-range optical sensors where non-contact detection up to 170 mm is required. The jump is worthwhile when an application demands IP67 sealing, infrared LED reliability and a fast 2 ms switching speed in a compact 75 mm cylindrical body. It is not suited for applications needing longer range, PNP output or alternative mounting formats.

Questions about this item

Which sensing range version suits my application best?

The sensor detects from 3 mm up to 170 mm under normal conditions, with a maximum reach of 200 mm; choose based on the distance your target will sit from the angled cylindrical head.

What does the 2 ms response time mean on the production line?

The output switches within 2 ms of detecting a change, so the sensor can reliably track objects moving at typical conveyor speeds without missing counts.

How does the M12 4-pin connector limit the installation?

The M12 4-pin male connector carries the 10–30 V DC supply and NPN dark-switching output, so cabling must match that pinout and voltage range.
