Time-of-Flight Sensors for Precise Distance Measurement – der wintec.

Time of flight (ToF) laser distance sensors with wintec (wenglor interference-free technology) have played a formative role in countless industries worldwide for over ten years. Thanks to integrated DS technology, the new generation of these sensors once again sets standards in terms of precision, performance, interference immunity, communication capability and robustness. The transit time sensors, also known as laser distance sensors, detect objects regardless of color, gloss, surface structure and inclination angle.

wintec with DS Technology
(Dynamic Sensitivity).

Compared with traditional transit time technologies, the latest wintec generation uses “Dynamic Sensitivity” (DS) technology. The laser distance sensor emits very short laser light pulses in the nanosecond range, with signals that are statistically evaluated and thus produce the distance value to the object.

  • Unrivaled reception sensitivity
  • Large working range of up to 10,000 mm
  • Reproducibility as low as 3 mm
  • Highly insensitive to ambient light of up to 100,000 lux
  • Insensitive to interference

Time of Flight Sensors in 316L Stainless Steel Housing

For extreme industrial environments, wintec is available in a high-quality stainless steel housing for the first time, which gives the position sensor even greater mechanical robustness at temperatures of −40 to +50 °C, as well as high chemical material resistance.

  • IP69K degree of protection via laser-welded housing
  • Resistant to cleaning agents with ECOLAB approval
  • Corrosion-resistant housing made of stainless steel 316L (1.4404/V4A)
  • Resistant to oils and lubricants

ToF Sensors for Performance and Precision

wintec – high performance – passenger cars

Large Working Range

The transit time sensor with DS technology impresses with a large working range of up to 10 m – regardless of whether the objects are light or dark, matt or shiny. The two independent switching outputs can be used, for example, to control signals for deceleration and stopping.

Detection of Transparent Objects

wintec with DS technology delivers reliable results even with very weak signals and thus impresses with the detection of transparent objects such as items of clothing packed in film.

Superior Detection and Maximum Precision

Thanks to DS technology, the ToF sensor also scores highly when it comes to detecting black and shiny surfaces, which are reliably detected even at extreme inclines. Even the smallest parts can be reliably detected from long distances with the fine laser beam and distances can be accurately measured.

Enlarged Laser Light Spot

The time of flight sensors have additional versions with an enlarged laser light spot. Thanks to this, the distance sensor can deliver stable measurement results even on very uneven surfaces. Objects with holes, tears or lattice structures are consistently and reliably detected by the large light spot.

Transit Time Sensors for Safety and Reliability

wintec – safety – resistance to ambient light

Extremely High Resistance to Ambient Light

Thanks to DS technology, time of flight sensors are extremely robust against disturbing ambient light up to 100,000 lux – reliable operation is guaranteed even in strong sunlight.

Hiding Interferences

The transit time sensor also works reliably in dirty environments. Disturbing ambient conditions such as dust and chips can be hidden. Interference factors in the background, such as reflective high-visibility vests, also do not affect the laser distance sensor.

wintec – communication – IO-Link

IO-Link 1.1 With COM3

Thanks to the integration of the latest IO-Link standards, the time of flight sensor can exchange process data with the control system at an extremely high transmission speed of 230.4 kBit/s.

Writing Process Data

The laser distance sensor can control important sensor functions via writable process data. The data is transmitted cyclically and time-consuming control programming is no longer necessary. This means that the laser light can be switched off, for example. Irritations in the interaction between man and machine are prevented and the laser light (laser class 1) is only activated when it is needed.
wintec – communication – operating software

Intuitive Operating Software and Selectable Measuring Unit

Whether metric or the Anglo-American measuring system – the wintec can output the distance values in millimeters or inches. These and other settings are possible via IO-Link and can be made conveniently via the wTeach graphic operating software.
wintec – communication – status messages

Extensive Status Messages

wintec with time of flight constantly monitors itself and outputs this information via numerous status messages. For example, temperature or ambient light warnings provide information on the current ambient conditions. The sensor also detects if its lens is dirty and provides information for preventive maintenance.
wintec – communication – acceleration sensor

Built-in Acceleration Sensor

The acceleration sensor built into the wintec detects impacts and shock loads. This can be used to detect, for example, whether a driverless transport system (DTS) has been subjected to a shock load due to a crash.
wintec – durability


The wintec measuring sensor is resistant to cleaning agents thanks to its robust 316L (1.4404/V4A) stainless steel housing with ECOLAB approval and high IP69K degree of protection, making it ideal for the wash-down area in the food industry.
wintec – durability


Thanks to their robust stainless steel housing, time of flight sensors are resistant to oils and coolants, as well as impacts, and are therefore particularly durable. This makes them ideal for use in harsh industrial environments. 
wintec – durability


The transit time sensor can efficiently withstand frequent and intensive cleaning with aggressive cleaning and disinfecting agents – even with high-pressure cleaning up to 100 bar and a water temperature of 80 ºC. 
wintec – durability


For applications in harsh environments with high levels of sparks – such as welding applications – the interchangeable PMMA lens with special coating provides increased protection of the distance sensor in a robust stainless steel housing. Lenses worn by welding spatter can be easily replaced. This means that no additional protective housing is required and the distance sensor does not need to be replaced.
