Hazardous Area Limit Switches
EX Series
UL. CSA. ATEX (CE). IEC Ex. INMETRO. NEMA 1. Div 1 & 2; Class I: B, C, D. Div 1 & 2; Class II: E, F, G
MICRO SWITCH EX Series switches feature the smallest UL-listed housings available for use in hazardous locations. The EX Series switch cavity is designed to cool expanding gases below the ignition temperature of the surrounding explosive atmosphere.
The EX Series is capable of switching up to 20 A while providing ample wiring space for ease of installation. Single and double conduit openings are available. Dual conduit openings may allow for through wiring of multiple switches. The EX Series can be mounted from any of the switch's four sides.
