Cylindrical M18 photoelectric proximity sensor

The Sick VTE18-4P2112 is a cylindrical photoelectric proximity sensor with an M18 × 1 thread and a 63.6 mm housing length. It operates on a 10 V DC to 30 V DC supply and uses an infrared LED to detect objects at distances from 3 mm to 170 mm. The PNP output supports light/dark switching selected via a control cable. It is suited for industrial automation tasks that require a compact axial-optic sensor.

Two-metre PVC cable and selectable switching

A 2 m four-wire PVC cable with 0.14 mm² conductors provides the electrical connection, removing the need for a separate connector. The L/D control cable lets the installer choose between light-on and dark-on behaviour without opening the housing. Switching frequency reaches 250 Hz with a 2 ms response time, and the output handles up to 100 mA. Built-in circuit protection covers reverse polarity, short-circuit, overload and inductive kickback.

Nickel-plated brass housing rated IP67

The metal housing is made of nickel-plated brass with a PMMA plastic optic, weighs 120 g and meets IP67 enclosure rating. It withstands ambient temperatures from –25 °C to +70 °C and carries UL file number NMFT2.E175606. The M18 thread allows direct mounting in standard threaded holes or with a locknut, while the axial optical axis keeps the sensing beam aligned with the cylinder centreline. Buyers who need a longer sensing range or a different output type should look for alternative models.

Questions about this item

What maintenance will the cable and LED light source need over time?

The 2 m PVC cable and infrared LED have no user-serviceable parts; inspect the cable jacket for abrasion and keep the PMMA lens clean for reliable detection.

Which limit appears first during continuous operation — the 250 Hz switching frequency or the 100 mA output current?

The 100 mA maximum output current is the hard electrical limit; the 250 Hz switching frequency only governs how fast the PNP output can toggle within that current ceiling.

How much heat and noise does the sensor produce when running all day at 30 V DC?

Power draw stays at 30 mA (Protection Class III), so heat is minimal and the solid-state design generates no audible noise during continuous use.
