Classification of climatic and mechanical environmental conditions additional protective coating for 420/460/490 series

3M7 1. General 2M2 25 g/6 ms30 g/11 msacc. to IEC 60068-2-27 Any device can be protected against special climatic and mechanical stress by an additional protective coating. This additional protective coating is identified by the letter “W” that is included in both the article number and the type designation. The application of device-specific product standards entailed minor changes of the previous values. The new values are listed in the table below. All new devices, of course, also comply with the characteristic values of the environmental tests used so far. 3.5 mm/2…9 Hz 1 g/9…200 Hz 1.5 g/200…500 Hz2 g/10…150 Hzacc. to IEC 60068-2-6 1M3 3 mm/2…9 Hz 1 g/9….200 Hzx Operating temperature Classification of climatic conditions 3K5 2K3 3M4 Classification of shock resistance 2M2 Classification of vibration resistance3K5 temperature-5…+55°C 2) relative humidity typ. 95 %, condensation and formation of ice possible temperature -25…+70 °C 10 g/11 ms15 g/11 msacc. to IEC 60068-2-27 10 g/11 ms 30 g/6 ms40 g/6 msacc. to IEC 60068-2-29
