Where other switching devices cannot cope, the products in our business field Extreme are in their element. They have been especially developed for use in extreme environments, e.g. high or low temperatures, explosive zones, very hygienic areas for foodstuffs or very dirty production halls. Examples from our comprehensive range include safety sensors in protection class IP 69K, vibration-resistant Hall sensors, immersion-resistant foot switches in protection class IP 68, robust emergency pull-wire switches for underground mining applications and salt fog-resistant position switches in protection class IP 66.
