Laser distance sensors in the AWL71 series
AWL71 series
The sensors of the AWL71 series are digital laser distance sensors for highest precision. They allow to measure at
a speed of 250 km/h the deflection of a car body for example. Owing to the special analog module most precise
measurements on almost all surfaces can be realized. Also the capture of small parts is possible due to the small
light spot diameter. The electronic of the sensors is placed in an external controller because of thet the weight
and dimensions have been significantly reduced. The separate electronic and the connection cable are included in
delivery.
• Measuring frequency 10 kHz
• Ethernet interface
• Analog output
• Ranges 0,5 mm up to 400 mm
• Low-noise
• Reliable results also with white/black transition
• Replacable protection glasses
