Industrial sensing with M18 housing
The Sick VTF18-3F1412 is a cylindrical photoelectric proximity sensor that uses background blanking to detect objects at short range. It supplies a PNP light-switching output and runs on 10 V DC to 30 V DC, drawing 30 mA. The radial optical axis and focused infrared LED produce a 3 mm light spot at 50 mm distance. A 270° potentiometer adjusts the sensing range between 3 mm and 90 mm.
Upgrade from basic diffuse sensors
This unit replaces simple diffuse sensors that cannot ignore reflective backgrounds or that lack a defined focus point. The jump is worth it when the application demands reliable detection on shiny or uneven surfaces within 90 mm and a switching frequency of 250 Hz. It also suits installations that need a metal nickel-plated brass housing rated to IP67 and an operating window from –25 °C to +70 °C.
Mounts in standard M18 threads
The sensor threads directly into M18 x 1 cut-outs and needs only a three-wire PVC cable for power and signal. Its 2 m cable with 0.14 mm² conductors frees the installer from buying separate connectors or junction boxes. The compact 60.6 mm body fits tight machine frames, while the 120 g weight adds minimal load to moving brackets or robotic arms.

Questions about this item
What thread size and housing length do I need to mount this sensor?
The sensor uses an M18 x 1 thread and has a cylindrical housing length of 60.6 mm.
How do I wire the three-wire cable and set the sensing range correctly?
Connect the 2 m PVC cable (brown to 10–30 V DC, blue to 0 V, black to the PNP load) and turn the 270° potentiometer to adjust the 3–90 mm range.
When should I replace the cable or clean the optics?
Inspect the Ø 3.1 mm PVC cable for wear and clean the PMMA optics if dirt reduces the 3–90 mm sensing range; the IP67 housing withstands –25 °C to +70 °C.
