TopWorx DXP Series Limit Switch

The TopWorx™ DXP Series are discrete valve controllers that can survive in virtually any plant condition. Its corrosion resistance and heavy-duty construction enables superior performance in the most demanding applications. These controllers carry IECEx, ATEX and UL certifications in a single model making it easier for global customers to standardize operations across their facilities. Engineered with GO Switch sensing technology, they deliver best-in-class capabilities. TopWorx GO Switches are hermetically sealed to outperform all other position sensors in hot, cold, wet, dirty, abusive, corrosive and explosive conditions. Its unique cam design allows quick and accurate setting of the GO Switch positions reducing deadband and hysteresis to a minimum.
