New contrast sensors for precise print mark detection

Thanks to the white light source and monochrome evaluation, they deliver stable measurement results with different contrast ratios, according to the Tettnang company.

The Wenglor Sensoric Group is expanding its portfolio with the P1MW contrast sensors. The new generation of sensors has been specially developed for standardised print mark detection in series applications.

With the P1MW series, Wenglor is presenting a new generation of compact contrast sensors that are tailored to the requirements of industrial series processes. The devices reliably detect print marks even with changing colours, materials and slight misalignments. Thanks to the white light source and monochrome evaluation, they deliver stable measurement results with different contrast ratios, according to the Tettnang-based company.

An integrated algorithm for step detection ensures that even the smallest signal changes are reliably detected - a decisive advantage with fluctuating material batches or varying brand colours. The dynamic teach mode enables automatic adjustment during operation and significantly reduces the set-up effort.

Compact design for tight installation situations

With dimensions of 54.5 × 27 × 16 millimetres, the P1MW sensors can also be used where space is limited. The small, homogeneous light spot ensures precise detection of even the smallest marks. An RGB status display directly on the device provides information on the operating status and facilitates diagnostics.

Communication via IO-Link 1.1

Process and diagnostic data can be read out, parameters copied and sensors clearly identified via IO-Link 1.1, according to the Tettnang-based company. The free wTeach2 software is available for further settings, which enables a clear visualisation of all parameters. According to Wenglor, the P1MW sensors therefore offer an economical and robust solution for demanding series processes in the packaging and printing industry.
