H series

With the H series, Schmersal presents a complete programme of control and signalling devices for hygiene-sensitive applications – especially for 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 control elements are easy to clean and so well sealed that they can withstand regular cleaning with devices such as high-pressure cleaners and aggressive cleaning agents.
The new series meets the requirements of DIN EN ISO 14159 and the latest version of EN 1672-2. This standard sets out very precise specifications for the hygienic design of all control 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 range not only meets the requirements of the standards and ‘hygienic design’ construction principle but is fully modular as well. Thanks to snap-on contact carriers and individual contacts which can also be combined (also in the Huckepack principle), this concept enables very easy and rapid installation as well as maximum flexibility and the ideal preconditions for pre-wiring.
A total of 147 different devices are available, including 26 mushroom pushbuttons, 24 selector switches with two or three positions and four potentiometer-rotary switches. The designer of a food-processing machine can freely decide which type of control element from the H range he wishes to use for the design of the HMI. With its wide range of different hygienic switchgear devices, the H range is unique to the market.
