Overview The Safety light-beam sensor L4000 system consists of the UE401 safety evaluation device and photoelectric safety switches. The UE401 safety evaluation device functions as the link between the photoelectric safety switches and the machine controller. It m Even complex protection tasks can be performed due to the ability to connect up to 8 sensor pairs, a range of versions that can be selected according to requirements, suitability for outdoor applications and the use of deflector mirrors. At a glance Type 4 (IEC 61496), SIL3 (IEC 61508), PL e (EN ISO 13849), only in conjunction with UE401 Small M18 sensors with ranges up to 10 m Compact M30 sensors with ranges up to 60 m Enclosure rating IP 67 Temperature range from –20 °C ... 55 °C Narrow evaluation Your Benefit Easy integration due to small, compact designs with maximum scanning range Flexible device integration makes it possible to set up individual access protections Fast response times reduce the safety distances and save production space Well-suited to extre Applications Access or area protection on machining centers and robot cells Monitoring of doors and service openings on machines Optical safety edges for protecting automated guided vehicles Note Product details cover the whole product family.
