About This Product

The SF45/B uses an oscillating single laser beam to scan the surrounding area rather than measuring only in one fixed direction. Its scanning angle can be configured according to the application, making it useful when a wider area needs to be monitored from a small sensor.

The sensor can produce up to 5,000 distance readings per second and up to 5 scanning sweeps per second. It also supports first- and last-pulse processing for applications where more than one reflecting surface may be present.
