Sick VTF18-3F5240 Photoelectric Proximity Sensor PNP

SKU CH-S7E6-1XFJT

Photoelectric proximity sensor detects objects up to 45 mm using focused infrared optics in an M18 nickel-plated brass housing rated IP67 with PNP light-switching output

  • Reliable detection with background blanking up to 45 mm
  • Focused infrared LED spot of Ø 3 mm at 25 mm distance
  • Adjustable sensing range via 270° potentiometer
  • Fast 250 Hz switching frequency with 2 ms response time
  • Rugged IP67-rated nickel-plated brass housing for harsh environments

Sick VTF18-3F5240 Photoelectric Proximity Sensor PNP

This new Sick VTF18-3F5240 is a cylindrical photoelectric proximity sensor with background blanking. It operates on 10 V DC to 30 V DC supply voltage and provides a PNP switching output with light switching mode. The sensor features focused optics with an infrared LED light source and a sensing range up to 50 mm. Its metal housing has an M18 x 1 thread diameter and an IP67 enclosure rating.

Ideal for industrial automation needing precise

Suits applications requiring background suppression within a 45 mm sensing range and a 250 Hz switching frequency. The potentiometer allows 270° sensing range adjustment for fine-tuning. Not suitable for installations needing longer detection distances beyond 50 mm or alternative output types such as NPN. Buyers requiring different connection types than the M12 4-pin male connector should look elsewhere.

M18 x 1 thread with 78 mm housing length defines

The cylindrical metal housing measures 78 mm in length with an M18 x 1 thread diameter for standard mounting. Axial optical emission produces a 3 mm light spot at 25 mm distance using infrared light. The sensor weighs 120 g and operates from –25 °C to +70 °C. Protection class III and IP67 rating ensure durability in harsh environments. UL File No. NMFT2.E175606 confirms compliance.

Questions about this item

Does the VTF18-3F5240 come with the M12 4-pin cable or must I buy it separately?

The sensor has a male M12 4-pin connector; the mating cable is not included and must be purchased separately.

Which sensing range figure should I use — 45 mm or 50 mm — when choosing this sensor?

Use 45 mm as the reliable sensing range; 50 mm is the absolute maximum under ideal conditions.

What does the 250 Hz switching frequency mean for my production line speed?

It allows up to 250 switching events per second, so the sensor can reliably detect objects spaced about 4 ms apart on a fast line.
