Industrial proximity sensor for automated detection
The Sick VTE18-3P2712 is a cylindrical photoelectric proximity sensor designed for industrial automation tasks that require reliable object detection. It operates on a 10 V DC to 30 V DC supply with a PNP light-switching output suitable for standard control systems. The sensor offers a sensing range from 3 mm to 170 mm with a maximum reach of 200 mm using infrared LED emission. Its 270° potentiometer allows precise adjustment of the sensing distance for specific applications.
Low power consumption with IP67 sealing
Power consumption is rated at 30 mA with a switching frequency of 250 Hz and a response time of 2 ms for fast signal processing. The enclosure rating IP67 protects the plastic PBT/PC housing and PMMA optics against dust ingress and temporary water immersion. Circuit protection covers multiple fault conditions while the unit weighs 100 g for minimal mechanical load. Operating temperature spans –25 °C to +70 °C for use in harsh environments.
M18 threaded mounting with fixed cable
The M18 x 1 thread diameter enables direct installation into standard mounting holes without additional brackets. A 2 m PVC cable with 3-wire 0.14 mm² conductors and 3.1 mm diameter provides a permanent connection that eliminates plug-related failures. Axial optical alignment emits a 10 mm light spot at 200 mm distance with a 2.8° dispersion angle for focused detection. Protection class III ensures safe low-voltage operation in industrial panels.

Questions about this item
How do I mount the M18×1 cylindrical housing and set the 270° potentiometer without over-tightening?
Screw the sensor into an M18×1 threaded hole or nut, hand-tighten then add a quarter turn with a wrench; adjust the 270° potentiometer while the target is at the desired distance, turning slowly until the output switches, then lock the setting.
What regular maintenance does the IP67-rated PBT/PC housing and PMMA optics need?
Wipe the PMMA lens with a soft lint-free cloth and mild detergent when dirt builds up; check the PVC cable jacket for cuts or kinks near the 2 m entry point and ensure the M18 seal remains tight.
At what point does the 250 Hz switching frequency limit detection during continuous operation?
The sensor cannot resolve events faster than 4 ms apart (250 Hz); if the target moves so that successive actuations would occur at shorter intervals, pulses will be missed.
