Sync-In / Trigger
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 beam is reduced, and the output signal is 4mA or 0V

To return the sensor to measuring 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

If Sync-In switches from high to low level, the response time lasts takes longer in the first
measurement cycle
Sync-In Level Measurement
Sync-In low 0…2.5 V Run
Sync-In high 8 V…UB (operating voltage) Hold
Application example: Reciprocal influence
Only the laser beam of Sensor1 may be in the measuring field of Sensor1. The laser beam of Sensor2 must
be outside the measuring field of Sensor1. This situation can happen if the sensors are mounted at an angle
to another, but especially when the sensors are facing each other. Such a situation should be avoided through
an appropriate installation if possible.
If it is not possible to prevent several sensors from affecting each other through appropriate installation, the
sensors can be operated asynchronously using the the Sync-In cable. The superordinate control generates
the signals for this.
