There may be variations at other temperatures.2) Average values, which depend on the application.3) The service life depends on the type of load. This is influenced by environmental conditions, the installation location, the measuring range in use, the traversing speed, and acceleration.AMBIENT DATA - BTFEMCAccording to EN 61000-6-2 and EN 61000-6-3Enclosure ratingIP64Operating temperature range–20 °C ... +70 °CCLASSIFICATIONSECl@ss 5.027270590ECl@ss 5.1.427270590ECl@ss 6.027270590ECl@ss 6.227270590ECl@ss 7.027270590ECl@ss 8.027270590ECl@ss 8.127270590ECl@ss 9.027270590ECl@ss 10.027270613ECl@ss 11.027270503ETIM 5.0EC001486ETIM 6.0EC001486UNSPSC 16.090141112113
