Hazardous Area Limit Switches
CX Series
UL. CSA. ATEX (CE). IEC Ex. INMETRO. IP66/67, NEMA 1, 3, 4, 4X, 6, 6P, 13. Div 1 & 2: Class I: B, C, D. Div 1 & 2: Class II: E, F, G
MICRO SWITCH CX switches are built especially for outdoor use in hazardous atmospheres. These enclosures are constructed to withstand the pressure of an internal explosion. Flame paths cool the exploded gases to a point less than the lowest safe operating temperature of the surrounding gas.
MICRO SWITCH 80CX Series switches have rugged bronze housings that are designed to be resistant to salt water and other corrosive environments. They comply with the NEMA 4X requirement for protection against corrosion, in addition to NEMA enclosure standards met by other CX switches.
The product's o-ring seals make the enclosure rain tight, but are outside of required flame paths so explosion proof requirements are maintained. Unless special ordered, all basic switches operate on clockwise and counterclockwise rotation. The actuating mechanism can be field adjusted for CW or CCW operation only. No tools are required.
