In the FREE 50 RS version a sonar is incorporated, it does the function of presence detection. This device operates with
ultrasound (not audible) at 42kHz. It can detect little objects at a few meters and big objects at more distance. For a good
detection of the obstacle, this has to be at an angle of 90º respect the sonar.
The presence detection signal, free contact input, allows connecting external presence detectors, like photocells or magnetic
detectors, and when the device detects a presence it activates the signal and enables the tag inside the activation field.
