(openPR) - Munich, 05 August 2011: “Safety matters” – is the motto under which Schaltbau GmbH will be appearing this year at SPS/IPC/DRIVES (22 to 24 November 2011) in Nuremberg. Key exhibits include the snap-action switches of the S850 and S880 series. The decisive factor for the development of the S850 series, a double NC contact switch, was the new DIN EN ISO 13849 standard, which is described in a new Machinery Directive of the European Union. The S880 snap-action switch, a V4 switch, features a positive opening operation mechanism as per the standard IEC 60947-5-1, Appendix K. These products satisfy exacting requirements in terms of safety, they are used in railway and industrial applications, e.g. as gear-type limit switches in crane systems and wind turbines. The product range on show will be rounded off by connectors, which have been specifically designed for outdoor conditions. Further information is available directly at our stand in hall 10.409 or online by visiting www.schaltbau-gmbh.de.

As a double NC contact switch, the S850 snap-action switch forms a redundant system. This is possible, since electrically isolated and mechanically linked contact bridges prevent incorrect power connection between two circuits. This means that two circuits can be switched that are on a different electrical level. These two circuits are opened synchronously, with a max. time difference of 3 milliseconds. The double NC contact switch incorporates a positive opening operation mechanism, which, within the scope of the requirements of the standard IEC 60947-5-1, Appendix K, also ensures opening after a short circuit (fail safe principle).

V4 switch with positive opening operation

The S880 series, a V4 switch, is the most compact snap-action switch with positive opening operation as per IEC 60947-5-1, Appendix K. Both switches have VDE, UL and CCC approvals.

Connectors for outdoors

Further exhibits include the connectors of the DN and M1 Plus series. The DN connector is a signal connector, available as both a plastic and metal version. Sealed to IP68 and IP69K, mated and unmated, it is exceptionally resistant to high-pressure cleaning. The product range is rounded off with the connector from the M1 Plus series. The M1 Plus is a universal industrial connector. This series is used for transmitting signals as well as for supplying components and systems with current. Connectors from Schaltbau are used in exclusive markets, which, for example, involve extremely harsh environmental conditions or demanding specifications. For example, in the food industry, environmental technology, traffic engineering and in machinery construction.
