The pushbuttons must withstand vibrations, temperature fluctuations and mechanical stress. Typical installation locations include machine control panels, mobile hand-held controls and control cabinets. The standardised 22.5 mm mounting cut-out allows for quick replacement during maintenance work.\r\n<h3>Automotive industry<\/h3>\r\nAssembly lines in the automotive industry require oil-resistant and high-density control elements. The components must be able to withstand cooling lubricants, cleaning agents and mechanical stresses caused by robots. Emergency stop functions with positively driven contacts are particularly important here to ensure maximum safety.\r\n<h3>Medical technology and cleanroom areas<\/h3>\r\nMedical devices require smooth, seamless surfaces to ensure hygienic cleaning. The control elements must be able to withstand disinfectants and steam sterilisation. Membrane pushbuttons and fully encapsulated designs with an IP69K protection rating meet these requirements. Tactile feedback is maintained despite the protective cover.\r\n<h2>Designs and standards<\/h2>\r\nDer Einbauausschnitt 22,5 mm nach DIN 43694 hat sich als Industriestandard etabliert. Diese Normung erm\u00f6glicht hersteller\u00fcbergreifende Kompatibilit\u00e4t und vereinfacht Lagerhaltung. Die elektrischen Eigenschaften folgen IEC 60947-5-1 f\u00fcr elektromechanische Steuerger\u00e4te und IEC 60947-5-5 f\u00fcr Not-Halt-Ger\u00e4te.\r\n\r\nBei Schutzarten reicht das Spektrum von IP40 f\u00fcr staubgesch\u00fctzte Innenraumanwendungen bis IP69K f\u00fcr Hochdruckreinigung mit 80\u00b0C hei\u00dfem Wasser bei 100 bar. Die Frontseiten erreichen diese hohen Schutzarten durch Dichtungen aus EPDM oder Silikon. Anschlussklemmen sind meist als Schraubklemmen f\u00fcr 0,5-2,5 mm\u00b2 oder als Steckklemmen ausgef\u00fchrt.\r\n\r\nKontaktmaterialien bestehen aus versilberten oder vergoldeten Kupferlegierungen f\u00fcr niedrige \u00dcbergangswiderst\u00e4nde. Die mechanische Lebensdauer liegt je nach Typ zwischen 100.000 und 10 Millionen Schaltzyklen. Alle Komponenten entsprechen REACH- und RoHS-Richtlinien f\u00fcr umweltgerechte Elektronik.\r\n<h2>B2B purchasing at E.Hartner<\/h2>\r\nBusiness customers benefit from tiered volume pricing and short delivery times from the central warehouse in Vienna.
