The portfolio for areas of application in rough environments has been expanded with the maintenance switches in stainless steel enclosures. The product line is ideal for use in the chemical industry, food production or building industry. Due to the various, sometimes aggressive dusts, varnishes or solvents, as well as the high demands in the hygiene sector, the components in these application areas are subject to extreme demands. The compact design, protection class IP66 and impact resistance IK08 are ideal for installation in tight spaces and under adverse environmental influences. As standard, entries for M20, M25 or M40 screw connections are provided in each enclosures. The right mounting accessories enable quick and cost-saving installation.
