Sick VTF18-3P1440 Photoelectric Proximity Sensor PNP

SKU CH-FG6P-NMASM

Photoelectric proximity sensor detects objects up to 100 mm with PNP dark-switching output and IP67-rated metal housing

  • PNP output simplifies wiring into 10–30 V DC systems
  • Sensing up to 100 mm detects objects at close range
  • IP67 enclosure resists dust and water ingress
  • Brass nickel-plated housing withstands –25 °C to +70 °C
  • 2 ms response time suits fast automation cycles

Sick VTF18-3P1440 Photoelectric Proximity Sensor

This Sick VTF18-3P1440 is a cylindrical photoelectric proximity sensor designed for industrial automation and electrician applications. It detects objects using an infrared LED light source within a sensing range of 3 mm to 90 mm. The unit features a PNP switching output with dark switching mode and a 2 ms response time. Its metal housing with brass nickel-plated finish and PMMA optics carries an IP67 enclosure rating for harsh environments.

Practical Limits of 10 V DC to 30 V DC Supply

The sensor operates on a 10 V DC to 30 V DC supply voltage with a maximum 10 % ripple and a power consumption of 30 mA. Voltage outside this range or excessive ripple will cause unreliable switching or permanent damage. The maximum sensing range of 100 mm applies under ideal conditions; the specified operating range is 3 mm to 90 mm. Ambient operating temperature is limited to –25 °C to +70 °C. The M12 4-pin male connector requires a matching cable assembly.

Check Your Existing Setup Before Ordering

Verify that your control system accepts a PNP dark-switching output signal compatible with the 2 ms response time. Confirm the availability of a 10 V DC to 30 V DC power source meeting the ripple specification. Ensure the mounting location accommodates the 75 mm cylindrical angled housing and M12 connector clearance. The IP67 rating suits wet or dusty areas but does not protect against all chemicals or high-pressure steam.

Questions about this item

How do I choose between the 3 mm to 90 mm and 3 mm to 100 mm sensing ranges?

The 90 mm figure is the rated sensing range for reliable detection, while 100 mm is the absolute maximum. Select based on the distance your application requires for consistent operation.

What does the 2 ms response time mean when the sensor is installed on a production line?

A 2 ms response time allows the sensor to detect objects and switch its PNP output within two milliseconds, suitable for high-speed automation tasks.

What does the M12 4-pin connector cap in terms of wiring and voltage?

The M12 4-pin male connector carries the 10 V DC to 30 V DC supply and the PNP switching output, limiting the interface to three-wire DC operation.
