LDS70A

Compact Distance Sensor

The LDS70A laser distance sensor is intended for general distance measurements which require extremely fast data acquisition.
It provides up to 40,000 centimeter-precise measuring values per second – up to 70 m without a reflector. With appropriate reflectors the LDS30A reaches objects at distances of up to 270 m.


Function

The sensor has been optimized for easy system integration and has a shock-proof and impact-resistant IP 67 housing. Thus, it is most suitable for applications that impose high impact on the sensor, such as harsh industrial environments.
Due to the invisible and eye safe laser (905 nm) the LDS70A can also be used in public areas.


Applications

  • Distance measurement
  • Fast object detection
  • Use as proximity switch
  • 2D and 3D scanning applications
  • Collision avoidance for drones
  • Altimeter

Features

  • Compact design, low weight
  • Extremely high measuring rate
  • Long measuring range
  • Eye safe operation
  • Housing in IP 67, shock-proof and impact-resistant
  • Industrial interfaces
  • Digital and analog outputs
  • Easy system integration
