Unmatched In Blue.
The World’s first ToF Sensor with Blue Laser Light

The P1PY21 series redefines the limits of sensor technology: as the world’s first time-of-flight sensors with blue laser, they deliver precise measurement results even under extreme conditions. Thanks to its shorter wavelength, blue laser light does not penetrate as deeply into the object surface, enabling stable detection of dark, glossy, organic and (semi)transparent materials. An integrated special filter minimizes interference from high-emitting objects such as glowing metals and ensures reliable detection even in demanding industrial environments. This combination of innovation and precision makes wintec with blue light the ideal solution for complex applications in automation technology.

Innovative BlueLine Technology

  • Short wave blue laser light with 445 nm wavelength for demanding surfaces

  • High accuracy on shiny plastics, dark paints or polished metals

  • Reliable detection of red glowing surfaces

  • Reliable detection of organic materials due to the reduced penetration depth of the blue laser

Large Laser Light Spot

  • Stable measurement results on uneven surfaces thanks to large laser light spot

  • Linear laser light spot with dimensions from 150 to 65 mm at a distance of 5 meters

  • Reliable detection of test objects with holes or tears

  • Reliable detection of grid structures thanks to wide detection range

Advanced Features for Every Measurement Task

Dynamic Jump Detection
Jump detection detects changes in the measured value instead of absolute distances. It enables accurate copy counting, detects flat objects on uneven surfaces and is suitable for edge counting.
Intensity Evaluation
Intensity evaluation can be used to detect the finest contrasts based on the reflected luminous intensity. It guarantees exact part inspection according to height and color and ensures reliable fault detection.
Integrated Speed Measurement
Speed measurement with ToF sensors is non-contact and wear-free. It detects movements over very long distances regardless of the surface of the test object.
Outstanding Precision
High black sensitivity and optimized angular behavior enable reliable detection of black, glossy and sloping surfaces with high reproducibility.
Large Working Range
With a range of up to 5 meters, the ToF sensor detects objects precisely, whether they are light, dark, matt or glossy. A switching and an analog output enable simultaneous object detection and distance measurement.
Transparent Object Detection
Laser distance sensors with wintec achieve precise results even with very weak signals and thus impress with the detection of transparent objects.

Reliable Distance Measurement at the Highest Level

The P1PY21 series uses the Dynamic Sensitivity (DS) technology to accurately detect objects over long distances. The sensor emits ultrashort laser light pulses and statistically evaluates the signals to determine the exact distance value.
With a measuring range of up to 5,000 mm and a reproducibility of only 3 mm, the sensor delivers reliable results even under difficult conditions. High ambient light resistance up to 100,000 lux and immunity to interference ensure maximum stability in challenging environments.

Smart Operation for Fast Results

Ease of Use at a Glance

Thanks to the high-contrast OLED display, the measurement data can be read easily even in difficult lighting conditions. Parameter configuration takes place directly via the clear menu, which makes initial startup and adjustment particularly user-friendly.

Advanced Control via Bluetooth

The integrated Bluetooth functionality enables wireless parameterization and data transfer via the weCon app. This provides an efficient solution, especially for hard-to-reach sensors or large-volume installations, as the sensors can be configured remotely.

Further Applications of BlueLine Technology

Firebed Monitoring in Pellet Kilns


In pellet kilns, the firebed height must be continuously monitored in order to control the heating efficiency optimally. This is where time-of-flight laser distance sensors with blue lasers are used. Thanks to the short-wave blue laser light, the large light spot and a special filter that filters out disturbing radiation, they reliably measure the distance to the firebed and deliver stable measurement results even on the uneven surface of the glowing pellets. This allows the combustion process to be optimally controlled and the heating efficiency to be continuously monitored and improved.

Fill-Level Monitoring of Bulk Material


Injected plastic parts are often transported as bulk material and filled into a material bunker for further processing, separated and fed to the next production step. Continuous level monitoring of the bunker is essential for a smooth production flow. Due to their large linear time-of-flight laser distance sensors with blue laser deliver reliable results – even on uneven or inclined surfaces. Due to the large measuring range, the sensors are also suitable for a wide range of bunker sizes and operating environments.
