Explosion-proof housings upgrade standard optical sensorsLeuze electronic are extending its range of explosion-proof optical sensors with several new versions plus a range of innovative new protection housings. These housings can be fitted to Leuze's cost-effective standard sensors to enable their installation in potentially explosive atmospheres.

Sensors correctly mounted in the protective housing can be used in areas with a potentially explosive atmosphere consisting of a gas/air or dust/air mixture, which is expected to occur seldom and only briefly. These are Zone 2 (gas) and Zone 22 (dust) of Group II, category 3 according to the CENELEC classification. In Zone 22, the devices can be used with conductive and non-conductive dusts.

These sensors also comply with the new international Standards IEC EN 60079-15 Electrical apparatus for explosive gas atmospheres.
