2D-/3D Profile Sensors
Number of
Profiles
Specifies how many profiles will be recorded before the sensor stops and can only
be restarted by a command or an input signal. Can be combined with the “Internal”,
“syncIN” and “Encoder” modes.
Sync Mode
• Internal: The sensor is triggered via the internally selected measuring rate.
Sample settings:
• Measuring rate: 200 Hz (i.e. one measurement every 5000 µs)
• Exposure time: 200 µs

Sync Mode
• syncIN: The sensor is triggered externally via the Sync IN pin function, e.g. by anoth-
er sensor or by an input signal. Only one profile per input signal is recorded and
transmitted.
Example with triggering via an I/O pin at the sensor:
• Sync In pin function: I/O3
• Input function, operating voltage: Rising edge
• Exposure time: 200 µs

NOTE!
In the case of time-critical applications and strict timing requirements for trig-
gering, the trigger signal via an I/O pin directly at the sensor must be used.
NOTE!
The applied input signal must be interference-free in order to assure flawless
functioning of the sensor.
