IDEM hazardous area safety devices provide similar functionality to their general-purpose counterparts but offer explosion-proof switching for use in hazardous locations. All of these devices are manufactured with ATEX Exd IIC T6 certified explosion-proof contact blocks which are encapsulated to contain explosions and prevent ignition of hazardous materials. New IDEM explosion-proof safety devices include tongue interlock safety switches, safety limit switches and safety cable-pull switches. These devices are an excellent choice for use in the oil, chemical, pharmaceutical and other hazardous industries. AutomationDirect has also extended its existing line of general-purpose safety cable-pull switches. This new line extension allows for emergency cable lengths of up to 250 meters. IDEM safety devices have a 1-year warranty.
