Industrial photoelectric sensor for 10 V DC to 30
The Sick VTF18-3N1412 is a cylindrical proximity sensor with an angled light emission design. It uses an infrared LED to detect objects at distances from 3 mm to 100 mm. The NPN dark-switching output activates when the beam is interrupted. An IP67-rated brass and plastic housing withstands temperatures from –25 °C to +70 °C.
Wiring and mounting requirements
A 2 m PVC cable with 0.14 mm² conductors and a 3.1 mm diameter carries power and signal. The sensor operates on 10 V DC to 30 V DC supply voltage with a 30 mA current draw. A potentiometer on the body allows sensing range adjustment without extra tools. The 60.6 mm housing fits into standard M18 mounting points.
Replaces older proximity switches
The 100 mm sensing distance extends detection beyond many legacy inductive or mechanical units. IP67 enclosure rating removes the need for additional protective shrouds in wet or dusty environments. The 2 ms response time supports faster line speeds than typical relay-output sensors. UL file NMFT2.E175606 confirms compliance for North American control panels.

Questions about this item
How far can the VTF18-3N1412 reliably detect an object before the 100 mm maximum sensing range becomes the limiting factor?
The sensor offers a sensing range of 3 mm to 100 mm, so the 100 mm upper limit is the first constraint you will reach under sustained use.
What is the power draw and heat rating when the sensor runs continuously on a 30 V DC supply?
Power consumption is specified as 30 mA with a 10 V to 30 V DC supply voltage; the enclosure is rated IP67 and the ambient operating temperature spans –25 °C to +70 °C.
Which mounting hardware and mating connector must I already have to install the cylindrical brass housing with its 2 m PVC cable?
The sensor uses a cylindrical, angled metal housing with a 2 m PVC cable (Ø 3.1 mm, 0.14 mm² conductors) and no plug, so you need compatible mounting brackets and a way to terminate the flying leads.
