Cylindrical angled metal sensor with M12 connector

Sick

Sick VTF18-3E5440 Photoelectric Proximity Sensor NPN

SKU CH-SED4-94569

Photoelectric proximity sensor detects objects up to 45 mm using infrared LED with NPN output, 10–30 V DC supply, IP67-rated brass housing, and M12 connector

  • Detects objects up to 50 mm away using infrared LED
  • NPN light-switching output responds in 2 ms
  • Adjustable sensing range via built-in potentiometer
  • IP67-rated metal housing withstands –25 °C to +70 °C
  • M12 4-pin connector simplifies installation on 10–30 V DC systems

Industrial Sensing Solution

The Sick VTF18-3E5440 is a photoelectric proximity sensor designed for automation tasks that require reliable object detection. It operates on a 10 V DC to 30 V DC supply and uses an NPN switching output with light-switching mode. The cylindrical, angled housing measures 75 mm and is built from nickel-plated brass and plastic for durability.

Adjustable Detection Range

A built-in potentiometer allows precise adjustment of the sensing distance between 0 mm and 45 mm, with a maximum reach of 50 mm. Infrared LED illumination and a 2 ms response time support consistent performance on fast-moving lines. The M12 4-pin male connector simplifies wiring, while the IP67 enclosure rating protects against dust and water ingress in harsh environments.

Suited For Compact Automation

This sensor suits engineers integrating presence detection into tight machine frames where an angled cylindrical form factor fits best. The operating temperature span of –25 °C to +70 °C covers most indoor and sheltered outdoor installations. Buyers needing longer sensing distances, PNP output logic, or a different connector style should look at alternative models.

Questions about this item

Will the potentiometer or the PMMA optics need periodic cleaning or replacement?

The potentiometer is sealed inside the nickel-plated brass housing and the PMMA optics are rated IP67, so neither component requires scheduled maintenance under normal conditions.

At the 50 mm maximum sensing range, does the 2 ms response time become the limiting factor for fast-moving targets?

The 2 ms response time is fixed across the full 0 mm to 50 mm range, so it determines the shortest detectable event regardless of distance.

How much heat does the sensor generate when powered continuously at 30 V DC?

Continuous operation at 30 V DC draws 30 mA; the metal housing and IP67 enclosure dissipate this low power without exceeding the 70 °C ambient limit.
