UL, IECEx & ATEX Encoders for Hazardous Areas

Hazardous area encoders are used where flammable liquids, vapors, gases or combustible dusts are likely to occur including oil & gas exploration, grain silos as well as paint and other chemical production. Dynapar offers several rotary encoders designed for these environments with varying degrees of zone and class/div protection ratings and certified by organizations including UL rated encoders, ATEX encoders, IECEx and CSA. Intrinsically safe encoders are used in conjunction with a barrier which limits the energy in the encoder so that any arcs or sparks do not have enough energy to ignite.
