The M4000 Advanced multiple light beam safety device together with the UE403 switching amplifier form the efficient solution for decentralised conventional muting applications involving automatic material transport.

Access protection with muting can be achieved with maximum availability thanks to their integrated functions, easily configured by PC via the RS-232 interface, and the simple in-situ connection of muting signals and control switches to the UE403.
The integrated functions, and status and diagnostic information, permit rapid commissioning and prevent unnecessary machine downtimes.

The modular concept provides a high level of machine safety that takes economic efficiency into account as device properties can be adapted to meet specific requirements.

This is especially the case for the M4000 Advanced A/P (active/passive) variants, with which only one requires electrical connection - considerably simplifying installation and cutting costs.
