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. The availability of the four cable entries, either metrics or imperial, provide a highly customizable solution meeting a wide range of applications. These include, but are not limited to, the Oil and Gas (both onshore and off shore) and Petrochemical industries.

Features:

•Twin shaft design, ensuring a complete sealed device: the shaft is splitted in two parts, each fitted and sealed into the body and cover for the best weather insulation even during opening operation.
•Suitable for artic application, down to -60°C.
•Enhanced flexibility of electrical feedbacks options.
•Up to four cable entries available in different sizes.
