- IP67-rated brass housing withstands water jets and dust
- 2 m PVC cable simplifies installation in tight spaces
Industrial photoelectric proximity sensor
The Sick VTE18-3P8212 is a cylindrical photoelectric proximity sensor with a PNP dark-switching output. It operates on a 10 to 30 V DC supply and detects objects using an infrared LED with a 2.8° dispersion angle. The metal housing is rated IP67 for harsh industrial environments.
Sensing range and cable constraints
Reliable detection spans from 10 mm to 700 mm, with a maximum possible range of 800 mm. The fixed 2 m PVC cable has a 0.14 mm² conductor cross-section and a 3.1 mm diameter, limiting routing flexibility and maximum cable extension. Supply ripple must stay below 10 % for stable operation.
Straightforward mounting with wiring care
The straight cylindrical body mounts easily via its M18 thread, and the potentiometer allows simple range adjustment. Common issues include overtightening the brass housing, damaging the cable bend radius near the entry point, or exceeding the 30 mA power budget on weak supplies.

Questions about this item
What does the 800 mm maximum sensing range mean when the sensor is installed in a machine?
The sensor can detect objects from 10 mm up to 800 mm under ideal conditions, while the practical sensing range is 10 mm to 700 mm for reliable operation.
How does the PNP switching output work with a 10–30 V DC supply?
The PNP output switches the positive supply voltage to the load when the sensor detects an object, operating within the 10 V DC to 30 V DC supply range with a 2 ms response time.
What does the IP67 rating cover for this cylindrical sensor?
The IP67 enclosure rating means the brass nickel-plated housing is dust-tight and protected against temporary immersion in water, suitable for harsh industrial environments.
