ReeR offers a full range of light curtains, light barriers, laser scanners, safety controllers and interfaces. The wide selection makes the catalog one of the most complete in the world of safety, thanks to the variety of models and especially to the application features studied according to the various needs of the users.
The company actively participate in several National, European and International (IEC) Standard Committees on Machine Safety. In this way, ReeR is always in the forefront about products standard compliance.
Today, not to mention the significant regulatory changes relating to the safety of the machines introduced since 2010, the design and construction of the security of a complex piece of machinery depends largely by economic factors and needs for flexibility.
Modular and configurable safety controller
Thinking about the current needs ReeR has created the modular safety integrate controller Mosaic. Safety level: SIL3 PL e. Mosaic is a modular, configurable safety controller for protecting machines or plants. Mosaic is capable of monitoring several safety sensors and commands including encoder and proximity for safety speed monitoring, concentrating management of these in a single, flexible device.
Mosaic comprises a master unit M1, configurable via the MSD (Mosaic Safety Designer) graphic interface – provided with each Master unit at no extra cost – and a maximum of 14 expansion units connectable to M1 via the MSC proprietary bus. The Mosaic system can be equipped with a maximum of 128 inputs,16 OSSD pairs, 16 feedback restart e/o interlock input and 32 signaling outputs. Expansion units are also available to permit connection for diagnostics purposes to the most common industrial Fieldbus systems.
Concerning in particular the sensors, the firm highlights the safety light curtains EOS4 and EOS2 that, with a section of only 28×30 mm, are one of the smallest light curtains on the market (with all integrated safety functions). They can be connected to Mosaic, safety dedicated interfaces, contactors controlled directly or safety PLCs. All models in the range have been certified for protection degree IP 65 and IP 67 – High resistance to infiltration by dust and liquids in a highly compact light curtain
Watertight enclosures allow EOS4 and EOS2 light curtains grids to be used in harsh working environments with exposure to water and steam. The small EOS WTF and WTHF cylindrical enclosure (only 56mm diameter) is IP 69K protection rate tested and can withstand up to 80 bar of water jets pressure at the temperature of 80°C.
Thanks to its inert (non-toxic) components, no residuals are left when the light curtains are washed down or when they come directly in contact with food. This makes WTF and WTHF enclosures suitable for the Food & Beverage industry. The EOS WTF e WTHF light curtains, suitable for the Food & Beverage industry have also been certified by: ECOLAB, passing the material resistance tests, according to the cleaning procedures for food and beverage industry.
