The SICK UE403-A0930 is a dedicated muting processing unit for the M4000 Advanced multi-beam safety light curtain family, enabling safe, standards-compliant muting of material flow in conveyor, packaging and palletizing cells. Designed for fast commissioning and reliable operation, it provides robust control of muting sequences while keeping personnel protection at the forefront.

Built for high functional safety, the UE403 meets Type 4 in accordance with IEC 61496-1 and achieves SIL 3, Category 4 and PL e in line with EN ISO 13849 and IEC 61508. The unit integrates synchronization monitoring, total muting time supervision, object gap suppression, band stop, override and comprehensive function monitoring, with the muting end controllable via the non-contact protective device. Clear LED diagnostics support maintenance, while a rugged die-cast aluminum housing with powder coating and an IP65 rating ensures durability in industrial environments from –30 to +55 °C. M12 5-pin sockets and a maximum cable length of 10 m streamline wiring in control cabinets and on machine frames.

Whether retrofitting an existing line or engineering a new machine, this muting controller simplifies integration with M4000 Advanced light curtains and typical 24 V DC architectures, and with a 1-year warranty it provides the reliability and assurance demanded in professional safety applications.
