Industrial proximity sensor for automated lines
The Sick VTF18-3N1440 is a cylindrical photoelectric sensor designed for object detection on conveyors and packaging equipment. It operates on 10 V DC to 30 V DC supply and switches an NPN output in dark-switching mode when a target enters the infrared beam.
Consistent detection across the sensing window
The sensor maintains its specified 3 mm to 90 mm sensing range during continuous operation with a 2 ms response time. Power consumption stays at 30 mA and the 10 % ripple tolerance keeps the output stable under typical industrial supply fluctuations.
Brass housing with M12 connector for harsh
The nickel-plated brass barrel and PMMA optics meet IP67 enclosure rating, resisting coolant spray and dust in machine frames. A 4-pin M12 male connector allows quick replacement without rewiring, while the –25 °C to +70 °C temperature range covers unheated factory floors.

Questions about this item
How much power does the VTF18-3N1440 draw when running continuously on a 24 V supply?
The sensor consumes a maximum of 30 mA from a 10 V DC to 30 V DC supply, so on 24 V it stays within that 30 mA limit.
What cable or connector do I need to wire the M12 4-pin plug on this sensor?
A standard M12 4-pin female cordset matches the male connector on the housing; no proprietary cable is required.
Will the brass nickel-plated housing and IP67 rating survive next to older oily machinery running at 60 °C?
Yes, the metal housing and IP67 enclosure are rated for ambient temperatures up to +70 °C, covering that environment.
