SICK VTE18-3N8440 Photoelectric Proximity Sensor NPN 10-30V DC

SKU CH-KB1V-GPTQ8

Photoelectric proximity sensor detects objects from 10 mm to 800 mm with NPN output and IP67 metal housing for 10–30 V DC supply

  • Photoelectric proximity detection up to 800 mm range
  • NPN dark-switching output for reliable object sensing
  • 10-30 V DC supply suits industrial power systems
  • IP67-rated metal housing withstands harsh environments
  • 2 ms response time enables fast automation cycles

Industrial Sensing Solution

The SICK VTE18-3N8440 is a photoelectric proximity sensor designed for automation engineers and maintenance technicians who need reliable object detection in industrial environments. Its cylindrical angled housing with metal brass nickel-plated construction suits machine builders integrating presence sensing into conveyor systems or packaging equipment.

Detection Range Constraints

The sensor operates with a maximum sensing range of 10 mm to 800 mm and a practical sensing range of 10 mm to 700 mm using infrared LED emission at a 2.8° dispersion angle. Dark switching mode activates the NPN output when the beam is interrupted, while the 2 ms response time sets the minimum detectable object speed for reliable switching.

Voltage and Connection Decider

This unit requires a 10 V DC to 30 V DC supply with 10 % ripple tolerance and connects via an M12 4-pin male connector. The IP67 enclosure rating and operating temperature span of –25 °C to +70 °C determine whether the sensor survives the specific electrical and environmental conditions of your application.

Questions about this item

What sensing range should I expect for typical targets with this VTE18-3N8440 sensor?

The sensor detects objects from 10 mm up to 700 mm under normal conditions, with a maximum reach of 800 mm depending on target reflectivity.

How fast does the NPN output switch after detecting an object?

The response time is 2 ms, so the dark-switching NPN output changes state within two milliseconds of a target entering the beam.

What does the M12 4-pin connector limit in terms of wiring and voltage?

The 4-pin M12 plug carries the 10–30 V DC supply and the NPN switching signal, cabling the sensor directly to a compatible PLC or relay input.
