Selector push-button switch H series

sensitivestandardsealed

The H series from Schmersal will be showcased – Smart Production Solutions – as a full range of new command and signalling devices for hygiene-sensitive applications, particularly food processing. Characteristic features of the range of command and signalling devices are gap-free transitions between sealing elements and surfaces and an absence of protruding parts. The command elements are easy to clean and so well sealed that they can withstand regular cleaning with high-pressure cleaners and aggressive cleaning agents. The new series meets the requirements of DIN EN ISO 14159 (Safety of machinery - Hygiene requirements for the design of machinery) and the latest version of EN 1672-2 (Food processing machinery - Basic concepts). This standard sets out very precise specifications for the hygienic design of all command elements at the human-machine interface (HMI) of food-processing machinery. Also taken into consideration was a new regulation, which formulates the requirements relating to the selection of materials for this particular area of use (Regulation 10/2011/EU). The new H series replaces the N range, which has been used globally at the HMI of food-processing machinery. The new range of command devices offers a range of different switchgear, including pressure switches, lamp indicators, selector switches, master switches and emergency-stop devices. The new H range not only meets the requirements of the standards and ‘hygienic design’ construction principle but is fully modular as well.
