UL-certified nonincendive Div 2 encoders, in six sizes from 2 to 4-1/2 in. with hollow or normal shafts, are compliant to CENELEC/ATEX and IECEx non-sparking Zone 2 hazardous-area standards. The nonincendive/non-sparking protection method assures that no sparking or hot surfaces will occur in the encoders under normal operating conditions, so there's no need for a barrier and no restriction of energy to the hazardous location.
