Description
Heavy-duty limit switch boxes, designed for hazardous areas, provide a visual and electrical remote position feedback on automated valves.
Available in die cast aluminum matching the Ex d IIB T6 standards. The SX/SH is our solution reaching Ex d IIB T6 or Ex d IIB + H2 T6 requirements. Thanks to spare pass through terminals, the three cable entries either metrics or imperial and different visual position indications, 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
- Metallic Self Lubricating Bushings
- Aluminium Enclosure with Thick Protective Powder Coating
- Up to 3 Cable Entries either Metric or Imperial
- Multiple Indicator Options
