Precision, Performance and Usability in One CMOS Laser Triangulation Sensor

The innovative triangulation laser distance sensors from the Wenglor P3 series provide precise measurement results at distances of up to 1,000 mm – accurate to a few microns. It’s not just the high accuracy that’s world-class, but also the intuitive operation concept, the high-quality aluminum housing and the built-in TripleA technology that gives the P3 series the status of gamechanger for triangulation sensors in industrial automation.

TripleA Technology Provide Top Performance

The P3 series is much more than just a technical update for Wenglor’s CP series, which has been established over many years. With TripleA technology, Wenglor engineers have included three technological building blocks that take the performance of the sensors to a new level. The ‘Aspheric Dual Lens’, offers two specially shaped aspherical lenses, ensures improved image quality of the laser light spot and thus increases optical precision. ‘Adaptive autoexposure’ enables the exposure time of the CMOS chip to be adjusted automatically. This makes it possible to expose both bright and dark objects, regardless of the material, to achieve good results. ‘Active Temperature Control’ ensures temperature-stable operation. Several temperature sensors built into the housing continuously measure the internal temperature. The warm-up time of CMOS sensors is significantly shorter compared to other sensors of this type. “TripleA technology not only increases the accuracy of the P3 sensors, but also makes them faster and more efficient,” emphasizes Wenglor product manager Christoph Lang. “Customers therefore benefit threefold from this innovation.”

Model Variety and User-Friendly Operating Concept

The P3 series comprises 32 models in total, divided into five measuring ranges for small and large distances from 30 mm to 1,000 mm. The high-quality aluminum housing, the glass lenses protected by a PMMA disc and the built-in temperature sensors ensure high temperature stability and short warm-up phases. P3 sensors can be supplied with either red or blue laser light, and are also available as digital or analogue versions. The digital models can be configured directly via teach-in, the analogue models via OLED display or via an integrated Bluetooth interface. Both variants are set via the intuitive operating concept: All sensor settings can be carried out by pressing a button for two or five seconds without operating instructions. The IO-Link 1.1 communication standard with the highest transmission speed COM3 also enables measurement data to be read out quickly. The power of the laser can even be changed to adapt the sensor to individual requirements: The P3 sensors are supplied in laser class 1 and can be switched to laser class 2 via a license. “The P3 series not only features some performance-enhancing technologies, but also impresses with its intelligent overall concept of performance, user-friendliness and fast communication. All of this on a sensor platform is currently unique on the market,” says Lang.

Precision Expert – Special Applications with High Requirements

The CMOS sensors from the P3 series are used wherever high optical precision in the micron range is required, where there is hardly any installation space available or where fine mechanical fluctuations are part of everyday life. Two sensors calibrated to each other can be used for width or thickness measurement. Just one sensor is sufficient to precisely position sheet material. But even complex objects with irregular, glossy and reflective surfaces in different colors, such as PCBs or weld nuts, can be reliably detected. The sensors from the P3 series are also real experts in double layer detection – for example of wafer-thin metal plates in the automotive industry.
