Safety relay meets latest elevator safety standards
With the aim of providing further improvement to the already high elevator safety standards, the safety requirements when constructing elevator systems will be tightened in the future. Elevator controls across Europe must conform to the new higher standards of the EN 81-20 regulation, by September 1.
Phoenix Contact's new PSR-MC37 safety relay from its PSRmini product range already fulfils theses heightened safety requirements. The safe switching device is just 22.5mm wide and is used to bridge door and locking mechanisms safely.
The EN 81-20 standard defines the requirements for construction and the technical properties of elevators. A new guideline states that the potential for risk should be reduced in glass doors, preventing small hands from becoming trapped. Furthermore, all elevators must be equipped with light grids on the doors and ensure improved stopping accuracy.
Threshold values when dimensioning air clearances and creepage distances in safety-related circuits have also been increased.
