Cylindrical angled metal sensor with M12 connector

Sick

Sick VTF18-3E5340 Photoelectric proximity sensor NPN

SKU CH-6AZK-VDEMZ

Detects objects up to 45 mm away using infrared light, with NPN output and IP67 protection

  • Detects objects up to 45 mm away using infrared LED
  • Adjustable sensing range via potentiometer for flexible setup
  • NPN light-switching output with 2 ms response time
  • IP67-rated brass housing withstands dust and water immersion
  • Operates reliably from –25 °C to +70 °C on 10–30 V DC

Industrial proximity sensor

The Sick VTF18-3E5340 is a photoelectric proximity sensor designed for industrial automation and machine monitoring. Its cylindrical angled housing measures 75 mm and fits tight mounting spaces on conveyors or packaging lines. The sensor operates on 10 V DC to 30 V DC supply voltage with a maximum power consumption of 30 mA. It suits engineers who need reliable object detection without physical contact.

Simple M12 connector mounting

Installation uses a male M12 4-pin connector that plugs directly into standard industrial cable assemblies. The metal brass nickel-plated housing with plastic optics withstands IP67 ingress protection for wash-down environments. A potentiometer provides sensitivity adjustment for the 0 mm to 45 mm sensing range. Common issues include misalignment of the infrared beam and incorrect NPN wiring polarity in the control cabinet.

NPN light-switching output

The sensor delivers an NPN switching output configured for light switching mode with a 2 ms response time. Maximum sensing range reaches 50 mm while the rated operating range is 45 mm using infrared LED emission. It functions across –25 °C to +70 °C ambient temperatures. Buyers requiring PNP output or dark-switching logic must select a different variant.

Questions about this item

How do I verify the sensor is operating correctly after wiring it to a 10 V DC ... 30 V DC supply?

The NPN light-switching output changes state when an object enters the 0 mm ... 45 mm sensing range; the response time is 2 ms and the amber LED on the housing indicates switching.

What comes in the box and what must be sourced separately for the VTF18-3E5340?

The sensor with its M12 4-pin male connector is supplied; a matching M12 female cable or field-wireable plug and a 10 V DC ... 30 V DC power source are not included.

Which sensing-range version should I choose for detecting targets up to 45 mm away?

This model provides a maximum sensing range of 0 mm ... 50 mm and a rated operating range of 0 mm ... 45 mm, so it covers the required distance without needing a different variant.
