- PNP dark-switching output handles 100 mA load
- IP67 enclosure resists dust and water ingress
- Operates reliably from –25 °C to +70 °C
Sick VTE18-3P4912 photoelectric sensor
The Sick VTE18-3P4912 is a cylindrical photoelectric proximity sensor with an M18 x 1 thread and a 60.6 mm housing length. It uses an energetic detection principle with infrared LED light and a radial optical axis. The sensor provides a PNP dark-switching output suitable for industrial automation tasks.
Check supply voltage and mounting clearance
Verify that your system supplies 10 V DC to 30 V DC with ripple below 10 % and can accommodate the 2 m PVC cable with 0.14 mm² conductors. Ensure the M18 mounting thread fits the intended bracket and that the radial light axis aligns with the target area within the 350 mm sensing range.
Suits presence detection in tight spaces
This sensor suits applications needing compact presence detection with IP67 protection and operating temperatures from –25 °C to +70 °C. It is not for buyers who require background suppression, analog output, or a longer sensing distance than 350 mm. Builders needing a connectorised version or a different switching mode should look elsewhere.

Questions about this item
What comes in the box with the VTE18-3P4912 sensor and what must be purchased separately?
The sensor includes a fixed 2 m PVC cable with three 0.14 mm² conductors. A 10–30 V DC power supply and any mounting bracket are not included.
How do I choose between the 350 mm sensing range and the 400 mm maximum range?
Use the 350 mm figure for reliable detection; the 400 mm maximum is only achievable under ideal conditions. Adjust the 270° potentiometer to set the exact switching point.
What does the 250 Hz switching frequency mean for my production line speed?
The sensor can change state up to 250 times per second, so it reliably detects objects spaced at least 4 ms apart on a fast conveyor.
