Description
About This Product
The SF20/C uses time-of-flight laser technology to measure the distance between the sensor and a target. Its compact design makes it suitable for applications where both sensor weight and installation space are limited.
The sensor can operate at configurable update rates up to 5,000 readings per second. It also provides first- and last-pulse processing, which can be useful when measuring through vegetation or when multiple reflecting surfaces are present.
