The MLG-2 Prime and SLG-2 sensors use optical synchronization instead of a wired connection. For this the device uses two SYNC beams. Both devices are designed for easy installation using standard cable plugs, no additional synchronization wiring between transmitter and receiver is required.

 

This differs from:

  • MLG Pro, relies on wired synchronization
  • SLG-2 FlexChain, synchronization is managed via the FlexChain host

 

All beams are clocked sequentially, Synchronization between transmitter and receiver is achieved through two dedicated SYNC beams.
As long as at least one of the two sync beams has a clear view, the system maintains full functionality.

What happens if both SYNC beams are blocked?

When both SYNC beams are blocked, a synchronisation error occurs (Event-Type: Warning). This impacts the sensor’s ability to determine the state of individual beams.

  • Presence Detection (Q-output):
    Still works because it does not require differentiation of individual beam states.

  • Measurement Functions:
    No longer available because the system cannot determine the exact state of all beams.
