Single shot
A single measurement is triggered with the falling edge of an external trigger signal at the Sync-In. This
measurement value is held at the outputs until the next falling edge. The measuring frequencies that can be
achieved are only half as high as in free-running mode.
Sync-In
The measurement and signal output can be interrupted with the Sync-In input by connecting with high. As long
as Sync-In is on high, the sensor delays the next measurement (hold) and reduces the power of the laser
beam.
•
The sensor checks Sync-In before every measurement
•
The previous measurement cycle is always completed first, even if Sync-In is on high
•
During the waiting time (Hold), the power of the laser beam is reduced
•
While Hold is at high, all outputs are frozen at their last state
•
To return the sensor to measurement mode, Sync-In must be set from high to low
•
Sync-In must remain on low for at least 5 µs in order for the sensor to begin measuring again

Application example: Reciprocal influence
Only the laser beam of Sensor 1 may be in the field of view of Sensor 1. The laser of Sensor 2 must not
influence Sensor 1.
If it is not possible to prevent several sensors from affecting each other through appropriate installation,
however, the sensors affecting each other can be operated asynchronously using the Sync-In cable. The
superordinate control generates the signals for this.
NOTE
As soon as the Sync-In is set to high (Hold), all output functions are frozen at their
last state until the next measurement.
