The 12CX200 is a single-pole double-throw (SPDT) explosion-proof Limit Switch with a side rotary momentary actuator and rugged cast aluminum housing. This MICRO SWITCH™ CX series switch is built especially for outdoor use in hazardous atmospheres. This enclosed switch is 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. The product's O-ring seals make the enclosure rain tight, but are outside of required flame paths so explosion proof requirements are maintained. The actuating mechanism can be field adjusted for CW or CCW operation only. No tools are required. it supports 0.75-inch - 14NPT conduit termination.
