The H series Hygienic command and signaling devices

New command device series
for food-processing

 

In the focus of development: hygiene, ergonomics and safety

The H series from Schmersal is a full range of new command and signaling devices for hygiene-sensitive applications, particularly food processing.  

Characteristic features of the range of command and signaling 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. Gaskets and seals between component parts are blue colored.

The line includes many types of command operators:

  • Emergency Stop button 
  • Pushbuttons 
  • Illuminated pushbuttons 
  • Indicator lights
  • Compact mushroom buttons, illuminated
  • Mushroom impact buttons 
  • Selector switches with 2 or 3 positions 
  • Step switches, 2-12 steps
  • Potentiometer drive knob 
  • Main switches, for 16A, 40A, 63A, or 125A

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 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 be combined (also in a piggyback system), 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 command device 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. In addition, and also new, the designer can order these command and signaling devices with individual laser marking, e.g. as an OEM version with logo.

Sanitary And Hygienic Design Standards

An overview of US and Canadian standards for food industry
Hygiene and sanitation are key issues in the food processing industry to prevent food borne illnesses. It influences the design of machines used in areas that need to be constantly cleaned. It is important when selecting safety devices or command devices for food processing machines that they meet hygienic or sanitary standards.
