Precise, Resource-Efficient and Process-Reliable – the New P1MW Contrast Sensors for Print Mark Recognition in Series Applications

With the new P1MW series contrast sensors, the wenglor sensoric group is presenting a resource-efficient solution for standardized print mark recognition. With clearly structured functions, the sensors can be seamlessly integrated into existing processes without any integration effort. The highly visible white light and precise monochrome evaluation ensure reliable contrast detection with a wide range of colors. Thanks to the integrated jump detection and dynamic teach, the P1MW sensors are particularly robust against process-related deviations. They deliver stable and precise results even with misalignments, different color combinations or changed brand colors – ideal for high volumes in series production. 

Contrast marks are used in many industries to ensure consistent product quality of packaging material. The contrast marks applied to the materials control a wide range of processes, such as sealing, cutting, folding or gluing. Reliable recognition of print marks is critical for keeping operations running smoothly. The requirements for contrast sensors are varied: In addition to limited mounting space and high belt speeds, process-related deviations, such as misalignments or changed brand colors, also impair process reliability. wenglor’s new P1MW series contrast sensors are ready for use in just a few steps and immediately ensure stable processes in series production. The sensors switch reliably even when the mark changes color or when different materials are used. Thanks to the integrated jump detection, signal changes in the contrast curve are detected and marks are reliably detected even with changing batches and applications. The compact M design makes it the ideal choice for tight installation situations.

Dynamic Teach and Precise Light Spot
The P1MW sensors learn during operation. Dynamic teach simplifies initial startup and ensures maximum efficiency in the series production process during setup and adjustment. The small, homogeneous light spot enables reliable detection of even the smallest marks. The highly visible white light and monochrome evaluation ensure optimal contrast values even with challenging color combinations. An RGB light provides instant feedback on sensor status for quick diagnostics directly on the device. IO-Link 1.1 can be used to read and write process data, identify the sensor, read out extensive status messages and duplicate parameter data. The free wTeach2 software provides an overview of all data and settings.
