SF-SS-SB Limit Switch Box Series

Brand: Soldo Controls
Limit Switch Box designed for safe and hazardous areas, provides a visual and electrical remote position feedback on automated valves. 

Available in either die cast aluminum, with different lid choices, from the same enclosure material, for a complete metallic device, to the transparent polycarbonate cover or to a flat lid without visual indication. Designed for weather proof applications, it can also matches the Ex ia. IIC T6 standards with the integral intrinsically safe certification, covering both enclosure and electrical components inside. 

The Soldo multi-application limit switch box solution, covering from industrial automation to food and beverage, from chemical to maritime, from oil and gas, both on-shore and off-shore, to petrochemical industries.
Features
  • Twin Shaft Design
  • Self Lubricating Bushings
  • Copper Free Aluminium or 316 Stainless Steel Housing Option for Maximum Corrosion Protection
  • 2 Cable Entries either Metric or Imperial
  • Multiple Indicator Options
  • Easy Wiring through the Terminal PCB Board
  • Position Transmitter Board Optional
  • Suitable for Artic Environments
