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.
Features- Twin shaft design, ensuring a complete sealed device: the shaft is split 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
- Enhanced corrosion resistance thanks to Copper free aluminum housing polyester powder coated (SY Series) or 316 stainless steel (SW Series)
- Easy wiring through the terminal PCB board
- NOVA V3 switch option ensures extreme durability and high power switching capabilities
- 4-20 mA position transmitter options
- Single tool opening design, allowing the operator to unscrew the lid by hand after removing the locker
