The sensors are distinguished by their innovative format, which allows dirt and cleaning agents to flow off them. A large number of components form a complete system that integrates seamlessly into the machine. The laser-welded 316L stainless steel housing (1.4404/V4A) is corrosion-free and resistant to cleaning agents. Mounted flush with a bayonet lock and fitted with undetachable optics, it is also ideal for environments that require a great deal of cleaning. Setting is performed by external teach-in.
