Sick VTE18-3N4312 Photoelectric Proximity Sensor NPN

SKU CH-MQCD-24DCX

A photoelectric proximity sensor detecting objects up to 350 mm with an NPN dark-switching output and IP67-rated metal housing

  • NPN dark-switching output suits sinking-input PLCs
  • 5 mm to 350 mm sensing range covers close and mid-range targets
  • Brass nickel-plated housing with IP67 rating resists water and dust ingress
  • 10–30 V DC supply works with standard industrial power rails
  • 2 m PVC cable allows direct wiring without extra connectors

Industrial Photoelectric Sensor

The SICK VTE18-3N4312 is a cylindrical photoelectric proximity sensor designed for industrial automation and control tasks. It operates on a 10 V DC to 30 V DC supply and provides an NPN dark-switching output for reliable object detection. The metal brass nickel-plated housing and IP67 enclosure rating suit harsh environments.

Upgrading From Basic Switches

This sensor replaces mechanical limit switches or lower-range optical sensors where non-contact detection up to 350 mm is required. The jump is worth it when applications demand a 2 ms response time, adjustable sensing via potentiometer, and resistance to vibration or contamination. It fits installations needing a compact angled design with a 2 m PVC cable.

Detection Range And Limits

The infrared LED detects objects from 5 mm to 350 mm reliably, with a maximum range of 400 mm and a narrow 2.8° dispersion angle. It handles ambient temperatures from –25 °C to +70 °C and draws a maximum of 30 mA. The sensor runs out of headroom beyond its specified sensing range, in environments exceeding the IP67 rating, or when supply voltage falls outside the 10–30 V DC window.

Questions about this item

What mounting hole size suits the 18 mm cylindrical housing of the VTE18-3N4312?

The sensor uses an 18 mm threaded barrel; drill an M18 clearance hole and secure with the supplied lock-nuts for a firm, aligned fit.

Which wire carries the NPN switching signal on the 2 m PVC cable?

The black conductor is the NPN output; connect it to the PLC input and the brown and blue wires to 10–30 V DC and 0 V respectively.

How often should the PMMA lens be cleaned in a dusty environment?

Wipe the lens with a soft, dry cloth whenever dust buildup reduces the 350 mm sensing range; the IP67 housing tolerates gentle compressed-air cleaning.
