Sick VTE18-3E8840 photoelectric proximity sensor NPN

Sick VTE18-3E8840 photoelectric proximity sensor

The Sick VTE18-3E8840 is a cylindrical photoelectric proximity sensor with an angled light emission design. It operates on a 10 V DC to 30 V DC supply voltage with a ripple of 10 percent and a power consumption of 30 mA. The sensor features an NPN switching output configured for light switching mode and a response time of 2 ms. It connects via a male M12 4-pin connector and is built with a plastic housing and PMMA optics material.

Sensing range up to 800 mm

The sensor provides a maximum sensing range of 10 mm to 800 mm and a defined sensing range of 10 mm to 700 mm using infrared light from an LED source with a 2.8° angle of dispersion. Distance adjustment is managed through a built-in potentiometer allowing precise configuration for the application. The enclosure carries an IP67 rating ensuring protection against dust and temporary immersion in water.

Suited for industrial automation needing NPN output

This sensor suits automation engineers and maintenance technicians requiring a compact cylindrical sensor with NPN light switching output for presence detection tasks. The 10 V to 30 V DC supply range fits standard industrial control voltage levels. Buyers who need a PNP switching output or a different connection type such as a cable gland should look at alternative models. The operating temperature range of –25 °C to +70 °C covers most indoor and sheltered outdoor environments.
