Industrial M18 photoelectric sensor
The Sick VTE18-3F8412 is a cylindrical photoelectric proximity sensor with a PNP switching output. It operates on a 10 to 30 V DC supply and detects objects using an energetic infrared LED principle. The housing uses nickel-plated brass with a PMMA optic and carries an IP67 enclosure rating. This unit suits automation engineers needing a compact presence detector for conveyors or packaging lines.
60.6 mm metal body with radial optics
The M18 x 1 thread allows direct mounting into standard tapped holes or brackets without extra hardware. A two-metre PVC cable with three 0.14 mm² conductors exits the housing, simplifying wiring in cable trays. The radial optical axis projects a 40 mm spot at the maximum 800 mm range with a 2.8 degree dispersion angle. Sensitivity is set via a 270 degree potentiometer on the sensor body.
Replaces older diffuse sensors with fixed ranges
The adjustable 10 to 700 mm sensing window covers distances that previously required multiple fixed-range models, reducing inventory for maintenance teams. A 250 Hz switching frequency and 2 ms response time handle fast cycling applications where slower relays would miss parts. The PNP light-switching logic integrates directly into common PLC input cards without signal inversion. Buyers needing background suppression or longer ranges should evaluate alternative sensing principles.

Questions about this item
What sensing range does the VTE18-3F8412 actually deliver?
The sensor detects objects from 10 mm up to 700 mm; the maximum possible range is 800 mm but the rated working range stops at 700 mm
What mounting thread and clearance does the M18 housing need?
It requires an M18 x 1 threaded hole, the barrel is 60.6 mm long and the cable exits radially so allow side clearance for the 2 m PVC lead
How do you set the sensing distance on the potentiometer?
Turn the 270° potentiometer while the target is at the desired distance until the output switches; the common mistake is adjusting with no target present which leaves the range unset
