Cylindrical angled photoelectric sensor with M12 connector

Sick

Sick VTE18-3E4940 Photoelectric proximity sensor NPN

SKU CH-G3P0-6XQ61

A photoelectric proximity sensor with an NPN switching output and a sensing range up to 400 mm

  • NPN switching output for direct PLC integration
  • Infrared LED with 2.8° dispersion for precise detection
  • Sensing range 5 mm to 350 mm covers close and mid-range
  • IP67 enclosure rating resists dust and water ingress
  • Operates from –25 °C to +70 °C in harsh environments

Photoelectric Proximity Sensor NPN

The Sick VTE18-3E4940 is a cylindrical photoelectric proximity sensor with an angled light-emission design. It operates on a 10 V DC to 30 V DC supply with a ripple tolerance of 10 %. The sensor provides an NPN switching output configured for light-switching mode and connects via a 4-pin M12 male connector. It is built for industrial automation tasks requiring non-contact object detection.

Sensing Range and Response Limits

The device offers a maximum sensing range of 5 mm to 400 mm and a defined sensing range of 5 mm to 350 mm using infrared LED light with a 2.8° dispersion angle. A potentiometer allows manual adjustment of the switching threshold. Response time is rated at 2 ms, setting the practical speed limit for detecting fast-moving targets in conveyor or packaging applications.

IP67 Enclosure Rating

The housing and optics are constructed from plastic, including PMMA for the optical elements, achieving an IP67 enclosure rating. This sealing protects against dust ingress and temporary water immersion in harsh environments. The unit operates reliably across an ambient temperature span of –25 °C to +70 °C. Buyers needing higher-pressure washdown ratings or metal housings should verify alternative models.

Questions about this item

Which sensing range should I choose for my application?

The sensor offers a maximum sensing range of 5 mm to 400 mm and a standard sensing range of 5 mm to 350 mm, both using infrared light with a 2.8° dispersion angle.

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

A 2 ms response time allows the sensor to detect objects and switch its NPN output within two milliseconds, suitable for high-speed counting or positioning tasks.

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

The M12 4-pin male connector requires a matching cordset and carries the 10–30 V DC supply, NPN switching output, and ground in a single IP67-rated connection.
