Why VTB18-4P1240?
Because it’s a “set-once, run-forever” photoelectric sensor: background suppression that shrugs off color changes, a bright red spot for painless alignment, a huge 270° trim for perfect tuning, and blistering ≤0.5 ms response at 1,000 Hz. Wrapped in nickel-plated brass with IP67 sealing and a plug-and-play M12, it’s built for fast lines and faster changeovers.
What problem does it solve?
Unreliable detection in messy, real-world factories. The VTB18-4P1240 isolates the target and ignores shiny conveyors, shifting backgrounds, and reflective fixtures. It keeps triggers crisp at short ranges, even when parts vary in finish or speed. Result: fewer false trips, fewer teach-ins, cleaner PLC logic (L/D selectable PNP), and dramatically less downtime during product swaps.

The Applications
1. Carton Detection on High-Speed Packaging Lines
In automated packaging lines, detecting fast-moving cartons accurately is essential to prevent misfeeds. The VTB18-4P1240 excels here with its background suppression, which distinguishes boxes from metal conveyor parts. Its ≤0.5 ms response ensures instant detection even at high speeds, while the bright red LED spot helps technicians align the sensor quickly. The 270° adjustable range control allows flexible setup for different carton sizes, minimizing false triggers and ensuring smooth synchronization with the filling or labeling stages.
2. Transparent Bottle Positioning in Beverage Lines
Beverage filling systems often struggle to detect transparent or light-colored bottles against shiny conveyors. The VTB18-4P1240 solves this with its adjustable 30–130 mm sensing range and strong background suppression that isolates the bottle from reflective surroundings. Its stable PNP output delivers consistent detection for precise fill timing, and the IP67 housing withstands frequent washdowns. Quick visual alignment using its visible red beam makes setup faster during production line adjustments or container size changes.
3. PCB Presence Verification in Electronics Assembly
In electronics production, ensuring a circuit board is correctly positioned before soldering or component placement is crucial. The VTB18-4P1240 can identify boards regardless of surface color or reflectivity, thanks to its fine-tunable background suppression. Its compact M18 housing fits easily into robotic arms or SMT fixtures. The fast 1,000 Hz switching frequency matches high-speed pick-and-place operations, reducing idle time and false readings while maintaining continuous workflow in precision environments.
4. Label and Print Detection on Corrugated Boxes
Printing and labeling systems require precise positioning control to maintain print quality. The VTB18-4P1240 detects printed or labeled areas on cardboard boxes without interference from background surfaces or mechanical frames. The visible red LED simplifies alignment for operators, and the quick response prevents skipped prints even at high belt speeds. Its robust metal housing resists dust and vibration, making it ideal for long-term use in printing, packaging, and logistics stations.
