Description
Heavy-duty limit switch boxes, designed for hazardous areas, provide a visual and electrical remote position feedback on automated valves.
Available in either copper free aluminum or 316 stainless steel, the explosion proof enclosure matches the Ex d IIC T6 standards. The SY - SW limit switch box series, thanks to its large inner volume able to host up to 6 switches and spare pass through terminals and the four cable entries either metrics or imperial, provide a highly customizable solution meeting a wide range of applications. These including, but not limited to, the Oil and Gas, both onshore and off shore, and Petrochemical industries.
