VTF18-4P1240 SICK 100 mm PNP – Axial Background-Blanking Photoelectric Sensor
- The VTF18-4P1240 is a SICK background blanking photoelectric sensor with a sensing range of 3–100 mm, designed for applications requiring high detection accuracy.
- Its background blanking technology ensures reliable object detection while minimizing interference from conveyors, machine frames, and background structures.
- The M18 cylindrical housing, nickel-plated brass construction, and IP67 protection rating provide excellent durability in demanding industrial environments.
- Featuring a PNP output, ≤ 2 ms response time, and 250 Hz switching frequency, the sensor is well suited for high-speed automation and production lines.
- Typical applications include packaging, food and beverage processing, electronics manufacturing, semiconductor production, industrial robotics, and logistics systems.
The VTF18-4P1240 is an axial background-blanking photoelectric sensor designed by SICK (Germany) for precise object detection in the 3–100 mm range, featuring focused optics with a 3 mm spot size, flexible PNP output, and IP67 protection.
Overview of the SICK VTF18-4P1240 Photoelectric Sensor
The VTF18-4P1240 belongs to SICK’s compact V18 cylindrical sensor family. The background blanking principle uses a fixed threshold to reject reflections from structures beyond the set detection zone — ideal for environments where the background is at a known, constant distance from the sensor.
The axial optical axis means the light beam travels along the sensor’s longitudinal axis (straight out from the front face), giving maximum flexibility for in-line and through-panel mounting configurations. The nickel-plated brass housing with M18x1 thread ensures robust mechanical integration into most standard sensor mounting brackets.

Industrial Applications of the VTF18-4P1240
Thanks to its 3–100 mm sensing range, focused optics, and rugged IP67 housing, the VTF18-4P1240 is widely deployed across Vietnamese manufacturing and automation facilities:
- Food & pharmaceutical packaging lines: Detect bottles, caps, and carton lids on conveyors. IP67 resists dust ingress and temporary water immersion, suitable for humid food-processing environments. For direct washdown, additional protection is recommended.
- Electronics & semiconductor manufacturing: Detect SMD components, PCBs, and wafers on conveyor jigs. The 3 mm focused light spot enables inspection of small parts without expensive specialized sensors.
- Industrial robotics & automation: Mounted on robot arms or inspection jigs to confirm part-in-gripper. Background blanking eliminates false triggers from structural backgrounds.
- Logistics & warehousing: Detects pallets, cartons, and totes. Sub-2 ms response time ensures fast throughput at sortation points.
- Printing & material processing: Detect paper, labels, and thin material sheets. The 270° potentiometer allows precise range tuning on-site.

*Guideline: Choose VTF18-4P1240 (axial) when the beam must travel along the sensor axis — typical in throughbeam-style setups or narrow channels. Choose VTF18-4P1440 (radial) when the sensor must be side-mounted through a panel or enclosure wall.
Frequently Asked Questions – VTF18-4P1240 SICK (FAQ)
Q1: What is the price of the VTF18-4P1240?
Pricing depends on quantity and delivery method. Contact AUMI at 0917 991 589 for the best quotation and model selection advice.
Q2: What industries use the VTF18-4P1240?
The VTF18-4P1240 is used primarily in food & pharma packaging, electronics & semiconductor manufacturing, industrial robotics, logistics, and printing — any application needing accurate detection of small objects in the 3–100 mm range.
Q3: What is the difference between VTF18-4P1240 and VTF18-4P1440?
The VTF18-4P1240 uses background blanking and an axial optical axis (beam along the sensor body). The VTF18-4P1440 uses background blanking and a radial axis (beam perpendicular to the body), suited for side / panel mounting.
Q4: Where can I buy a genuine SICK VTF18-4P1240?
AUMI is the official SICK distributor in Vietnam, guaranteeing 100% authentic products with full labels, CO/CQ, and traceable origin. Call 0917 991 589 or visit aumi.com.vn for technical advice and pricing.
Q5: Is the VTF18-4P1240 waterproof?
Yes. The VTF18-4P1240 carries an IP67 rating, meaning it is fully dust-tight and can be submerged to 1 m for 30 minutes. For high-pressure spray cleaning, use additional protective enclosures or select an IP69K-rated sensor.
