With the safety switching devices of the SR series, Zander offers a series that protects people and machines. They monitor the function of connected safety sensors and the wiring and work as a power amplifier to safely switch off connected contactors or drives.
From the emergency stop and protective door monitoring to 2-hand applications to firing systems in continuous operation, all safety switching devices of the SR series meet the requirements of the relevant standards and are certified by independent testing institutes such as TÜV Rheinland, Underwriters Laboratories (UL) or Germanischer Lloyd (GL) and CCC tested and certified.
No matter what industry you come from: we have the right safety relays, safety control units, safe time relays, coupling relays and expansion modules.
