The SICK VTE18-3P8240 photoelectric proximity sensor is a compact M18 infrared sensor designed for dependable, non-contact object detection in industrial automation systems. Using an energetic photoelectric sensing principle, it detects objects directly without reflectors, making it suitable for applications with varying target shapes and surfaces. With a sensing distance reaching up to 700 mm, a rugged metal housing, and high environmental protection, it addresses the common challenge of maintaining stable detection performance in dusty, vibration-prone, or temperature-variable production environments.
The SICK VTE18-3P8240 provides stable and repeatable detection by combining infrared LED technology with precise sensitivity adjustment, allowing engineers to fine-tune performance for different materials and background conditions. Its fast switching response supports moving objects on conveyors and automated handling systems without signal lag. The robust, nickel-plated brass construction ensures long-term reliability in demanding machinery, while the dark-switching PNP output enables straightforward integration with standard PLC inputs. In practical use, this sensor reduces false detections, improves process consistency, and helps minimize unplanned downtime across automated production lines.
Why SICK VTE18-3P8240?
The SICK VTE18-3P8240 is chosen when reliability, simplicity, and long-term stability matter more than complexity. Its energetic photoelectric principle allows direct object detection without reflectors, reducing installation effort and alignment time. The M18 metal housing fits seamlessly into standard machine designs, while fine sensitivity adjustment gives engineers precise control during commissioning. Designed for continuous industrial operation, it performs consistently even when dust, vibration, or temperature fluctuations would compromise lower-grade sensors, making it a dependable choice for professional automation environments.
What problem does it solve?
The SICK VTE18-3P8240 solves the challenge of unreliable object detection in real-world industrial conditions. In many applications, inconsistent surface reflectivity, ambient light interference, or mechanical stress can cause missed detections or false signals. This sensor delivers stable infrared detection with fast response, ensuring accurate presence sensing on moving conveyors, packaging lines, or assembly stations. By minimizing false triggers and maintaining repeatable performance, it helps prevent process interruptions, improves machine efficiency, and reduces maintenance-related downtime.

The Applications
1. Conveyor-Based Product Flow Monitoring
In automated conveyor systems, consistent object detection is essential to maintain smooth material flow and prevent system interruptions. The SICK VTE18-3P8240 is widely applied to detect cartons, bins, or components as they travel along conveyors at varying speeds. Its energetic infrared sensing principle allows direct detection without reflectors, even when product surfaces differ in color or finish. The fast response time ensures accurate detection of closely spaced items, while adjustable sensitivity helps avoid false signals from conveyor frames or background objects. The robust metal housing supports reliable operation in dusty and vibration-prone logistics environments.
2. Component Presence Verification in Automated Assembly
Automated assembly lines depend on accurate confirmation that each component is correctly positioned before the next operation begins. The SICK VTE18-3P8240 is commonly installed at assembly stations to verify part presence and alignment. Its infrared detection handles both reflective and non-reflective materials, reducing sensitivity to surface inconsistencies. The compact M18 form factor enables integration into tight mechanical layouts, and the dark-switching output simplifies PLC logic design. This application helps prevent incomplete assemblies, reduces scrap, and improves overall production reliability.
3. Position Detection in High-Speed Packaging Machines
Packaging machines require precise position feedback to synchronize sealing, cutting, and labeling actions. The SICK VTE18-3P8240 is frequently used to confirm the arrival of packaging materials at defined positions during fast machine cycles. Its short response time supports high-speed motion without detection lag, while adjustable sensing allows reliable performance with varying packaging materials. The sensor’s resistance to vibration and environmental stress ensures stable operation over extended production runs, helping packaging lines maintain consistent output quality with fewer unplanned stops.
4. Non-Contact Presence Sensing in Challenging Environments
In environments where dust, mechanical shock, or temperature fluctuations are common, mechanical switches often fail prematurely. The SICK VTE18-3P8240 is used as a non-contact alternative to detect object presence or machine positions in such conditions. Its sealed metal housing protects internal components, while infrared sensing maintains stable detection despite airborne particles. Adjustable sensitivity compensates for gradual environmental changes, reducing the need for frequent recalibration. This application extends sensor service life, lowers maintenance costs, and improves long-term automation reliability.
