  • IP67 brass housing withstands dust, water and –25 °C to +70 °C
  • Potentiometer adjustment and 2 ms response simplify set-up

Industrial proximity sensor for automation tasks

The Sick VTE18-3N2340 is a photoelectric proximity sensor designed for industrial automation and machine-monitoring applications. It detects objects within a 3 mm to 170 mm sensing range using an infrared LED with a 2.8° dispersion angle. The NPN dark-switching output and 2 ms response time suit programmable logic controllers and similar control systems.

Brass housing with IP67 rating and M12 connector

A cylindrical, angled metal housing made of nickel-plated brass and plastic provides IP67 enclosure protection against dust and water ingress. The optics use PMMA plastic. A four-pin male M12 connector enables quick, secure wiring in the field. A potentiometer on the body allows sensing-distance adjustment without tools.

Check voltage, output logic and mounting clearance

Verify that your control cabinet supplies 10 V DC to 30 V DC with ripple below 10 % and can sink the NPN dark-switching signal. Confirm the 75 mm housing length and angled light emission fit the available mounting space. Ensure the operating temperature window of –25 °C to +70 °C matches the installation environment.

Questions about this item

What supply voltage range does the VTE18-3N2340 sensor accept?

The sensor operates on 10 V DC to 30 V DC with a maximum ripple of 10 percent and draws up to 30 mA.

What mounting dimensions and connector type does the VTE18-3N2340 require?

It has a cylindrical angled housing 75 mm in overall size, a brass nickel-plated metal body, and connects via a 4-pin M12 male connector.

How is the sensing distance set on the VTE18-3N2340 and what common mistake should be avoided?

Adjust the potentiometer while the target is at the desired distance; the sensor switches on dark, so turning the pot the wrong way inverts the output logic.
