VTF18-4P1440 SICK 100 mm PNP – Radial Background-Suppression Photoelectric Sensor
- The VTF18-4P1440 is a SICK background suppression photoelectric sensor with a sensing range of 3–100 mm, designed for applications requiring accurate object detection at defined distances.
- Its background suppression technology effectively eliminates interference from background objects, ensuring reliable detection even in environments with varying surface reflectivity.
- The radial optical axis (side-looking design) enables easy installation on control panels, mounting plates, and applications requiring lateral object detection.
- Featuring a nickel-plated brass housing and an IP67 protection rating, the sensor is built to withstand harsh industrial environments with dust, moisture, and water exposure.
- With a PNP output, ≤ 2 ms response time, and 250 Hz switching frequency, the VTF18-4P1440 is well suited for automation systems, conveyor applications, and high-speed production lines.
- Typical applications include control cabinets, component assembly lines, packaging machines, industrial robotics, logistics systems, and conveyor-based material handling.
The VTF18-4P1440 is a radial background-suppression photoelectric sensor designed by SICK (Germany) for reliable detection in the 3–100 mm range, featuring focused optics, flexible PNP output, and IP67 protection.
Overview of the SICK VTF18-4P1440 Photoelectric Sensor
The VTF18-4P1440 belongs to SICK’s compact V18 cylindrical family. Background suppression uses optical triangulation to actively ignore reflections from any background beyond the set distance — giving consistent results even when background color or reflectivity varies, which is a common challenge in real factory environments.
The radial optical axis means the beam exits perpendicular to the sensor body. This is particularly useful for through-panel installations, cabinet mounting, or anywhere the sensor body runs parallel to the mounting surface while the beam points outward. The nickel-plated brass body with M18x1 thread fits standard 18 mm sensor clamps and brackets.

Industrial Applications of the VTF18-4P1440
The radial optical axis and background suppression capability make the VTF18-4P1440 the go-to sensor for side-mounted and panel-integrated detection:
- Electrical cabinets & control panels: Sensor body fits inside the panel; the radial beam exits through a drilled hole to monitor external conditions without protruding the full sensor length.
- Component production lines: Detect parts on jigs and pallets from the side. Background suppression accurately rejects signals from varying-reflectivity backgrounds, reducing false trips versus fixed-threshold sensors.
- Conveyor & pipeline systems: Side-mount along conveyor edges to detect passing product without interference from the structural frame behind.
- Counting & packaging machines: Count small items as they pass laterally. The 2 ms response time and 250 Hz frequency support medium-to-high-speed lines.
- Robotics & automation: Attach to robot arms with the beam pointing radially to detect gripped objects or nearby obstacles without complex re-orientation.

*Guideline: Choose VTF18-4P1440 (radial) when the sensor must be through-panel or side-mounted with the beam pointing outward from the body. Choose VTF18-4P1240 (axial) when a straight-on, inline mounting is needed.
Frequently Asked Questions – VTF18-4P1440 SICK (FAQ)
Q1: What is the price of the VTF18-4P1440?
Pricing depends on quantity and delivery method. Contact AUMI at 0917 991 589 for the best quotation and model selection advice.
Q2: What is the difference between VTF18-4P1440 and VTF18-4P1240?
The main differences lie in the optical axis orientation and installation style:
- The VTF18-4P1240 features an axial optical axis (beam emitted straight along the sensor’s longitudinal axis), making it ideal for applications where the object needs to be detected directly in front of the sensor.
- The VTF18-4P1440 features a radial optical axis (beam emitted perpendicular to the sensor body), which is well-suited for installation on control panels, mounting plates, or positions requiring side/lateral object detection.
In terms of sensing range, output type, protection rating, and overall detection performance, the two models are nearly identical. The choice between them primarily depends on the available mounting space and the required direction of object detection in the actual application.
Q3: What industries use the VTF18-4P1440?
The VTF18-4P1440 is used in control panel manufacturing, component production lines, conveyor & pipeline systems, counting & packaging machines, and industrial robotics — wherever side mounting and adaptive background rejection are needed.
