Sick VTE18-4P2440 M18 photoelectric sensor
The Sick VTE18-4P2440 is a cylindrical photoelectric proximity sensor with an M18 x 1 thread diameter and an axial optical axis. It operates on a 10 V DC to 30 V DC supply voltage with a maximum power consumption of 30 mA. The sensor uses an infrared LED light source and provides a PNP switching output with selectable light or dark switching via an L/D control cable. It is suited for automation engineers and electricians integrating presence detection into industrial control systems.
Potentiometer adjustment and M12 connector
A 270° potentiometer allows manual adjustment of the sensing range between 3 mm and 170 mm, with a maximum reach of 200 mm. The light spot measures Ø 10 mm at 200 mm distance with an approximate 2.8° dispersion angle. Selectable switching mode and a 2 ms response time at 250 Hz switching frequency support reliable object detection. The male M12 4-pin connection simplifies wiring in standard industrial fieldbus installations without requiring additional cable termination.
Nickel-plated brass housing with IP67 rating
The housing is constructed from nickel-plated brass with PMMA optics and weighs 120 g. An IP67 enclosure rating protects against dust ingress and temporary water immersion in harsh environments. Operating temperature spans –25 °C to +70 °C for use in unheated or outdoor locations. Circuit protection includes supply voltage, output short-circuit, and reverse polarity safeguards. UL file NMFT2.E175606 confirms compliance for North American panel builds.

Questions about this item
What maintenance does the M18 photoelectric sensor need over time?
No moving parts require service; periodically wipe the PMMA optic clean and verify the potentiometer setting has not drifted.
What limit appears first during continuous operation at 250 Hz?
The 2 ms response time and 250 Hz switching frequency cap the minimum detectable pulse width, so faster events may be missed.
How much heat and noise does the sensor produce when powered all day?
It draws 30 mA from 10–30 V DC with no fan or moving parts, so audible noise is absent and heat dissipation is minimal inside the IP67 nickel-plated brass housing.
