Wenglor Launches P1MW Series Contrast Sensors
In an era where precision and efficiency define manufacturing competitiveness, Wenglor, a global leader in sensor technology, has unveiled its groundbreaking P1MW Series Contrast Sensors, designed to eliminate costly errors in high-speed packaging and labeling operations. These compact, high-performance sensors address a critical pain point in automated production: the reliable detection of print marks on moving materials, even under challenging conditions.
Why Print Mark Detection Matters
On modern packaging lines processing thousands of items per hour, a single missed print mark can disrupt sealing, cutting, or labeling processes, leading to material waste, machine downtime, and costly rework. Traditional sensors often struggle with faint contrasts, color variations, or speed fluctuations, compromising accuracy. Wenglor’s P1MW Series redefines reliability by combining advanced optics, adaptive algorithms, and intuitive configuration tools.
Key Innovations Driving Performance
Ultra-Precise Detection:
The P1MW sensors feature a focused, uniform light spot and bright white illumination, enabling detection of even the smallest print marks (≤1 mm) on glossy, colored, or transparent surfaces. Monochrome evaluation ensures consistent accuracy across diverse material combinations.Dynamic Adaptability:
Built-in dynamic teaching functionality allows the sensors to self-adjust to changing conditions—such as material shifts or color batches—without manual recalibration. This reduces setup time and minimizes human error.Jump Detection for Stability:
A proprietary algorithm identifies sudden contrast changes, ensuring reliable mark detection even when materials vary between production runs. This feature is critical for maintaining alignment in continuous processes like tea bag folding or chocolate wrapping.Compact Design, Big Impact:
Measuring just 54.5 x 27 x 16 mm, the P1MW fits into space-constrained machines while delivering industrial-grade durability. Its RGB status indicator provides real-time visual feedback, and IO-Link 1.1 connectivity enables digital parameter duplication and remote diagnostics.
Industry-Specific Applications
The P1MW Series excels in demanding environments:
Tea Packaging: Detects print marks on folding films to ensure consistent gluing and cutting.
Chocolate Wrapping: Maintains precision at high conveyor speeds, preventing misaligned seals.
Sachet Filling: Adapts to glossy or colored materials, reducing waste in pharmaceutical and food packaging.
Models Tailored to Control Systems
Wenglor offers two variants to seamlessly integrate with existing infrastructure:
P1MW001 (PNP output): Ideal for sourcing input systems.
P1MW002 (NPN output): Compatible with sinking input systems.
Both models share identical optical and processing capabilities, eliminating the need for additional converters or rewiring.
Software and Support Ecosystem
Users gain access to wTeach2 software, a free tool providing real-time sensor data visualization and simplified configuration. This transparency empowers engineers to optimize performance without specialized training.
A Leap Forward for Automated Production
“Reliable sensors are the backbone of uninterrupted automation,” said a Wenglor spokesperson. “The P1MW Series isn’t just about detecting marks—it’s about enabling manufacturers to achieve zero-defect production with minimal intervention.”
By reducing setup time, adapting to color shifts, and preventing costly errors, the P1MW Series positions Wenglor at the forefront of Industry 4.0 innovation. As global demand for high-quality, sustainable packaging grows, these sensors offer a practical solution to enhance efficiency and profitability.
