Wenglor laser distance sensors
March 2021
Sensors & Transducers
Wenglor Sensoric has released its latest generation of long-range laser distance sensors. These transit time sensors, available in plastic or stainless steel 316L housings, have not only been given a big increase in performance with the integrated Dynamic Sensitivity (DS) technology, but also combine all the features of the popular Wintec series, which have been revolutionising the automotive industry since 2009.
A working range of up to 10 000 mm, maximum reproducibility of 3 mm and insensitivity to ambient light up to 100 000 lux are just some of the highlights of the new Wintec device. In addition, with the latest IO-Link 1.1 standard, numerous status messages such as temperature or ambient light warnings can be called up. Even impact and shock loads can be recorded.
Dynamic Sensitivity
The result of intensive R&D; in transit time sensors, the sensor emits very short light pulses, in the nanosecond range, with signals that are statistically evaluated and then produce the distance to the object. Even with very weak signals, the sensor generates precise measurements. This is the only way to achieve a working range of up to 10 000 mm while improving reproducibility to just three mm over the entire working range of the sensor. Added to this is that other sensors in the immediate vicinity of contamination do not influence each other due to the DS technology.
High-performance transit time technology
Long-range laser distance sensors detect objects based on the principle of transit time measurement, regardless of colour, gloss surface structure or inclination angle. This capability has made Wintec one of the most popular photoelectric sensors and an essential part of many automation processes. The sensors also work reliably from temperatures of -40°C, have a very short warm-up time, and LEDs on the front for integrated installations in shuttle systems, for example. Simple operation and low power consumption compared to conventional transit time sensors enables significant time and cost savings for user.
Plastic or stainless steel housings
A version in a corrosion-resistant stainless steel 316L housing with Ecolab approval is suitable for use in food industries. High-pressure cleaning up to 100 bar and water temperatures up to 80°C in the wash-down range are possible due to the laser-welded IP69K housing and chemical resistant plastic parts.
