Compact limit switch box, designed not only for the industrial market, but for indoor applications in hazardous areas.

Available in nickel plated aluminum, with flat lid or 3D indicator.

The SP is a corrosion resistant device, able to satisfy the requirements in water treatment and desalination plants; both SP and SM  match the Ex ia IIC T6 standards with the integral intrinsically safe certification, covering both the enclosure and electrical components inside.

With these devices we provide a ready to mount solution, thanks to the integrated Namur mounting kit.

• Glass reinforced resin enclosure with transparent polycarbonate lid, ensuring a device totally unaffected by corrosion, in salty and humid atmospheres.
• One cable entry as standard, for the SP series, and two cable entries, for the SM, either metric or imperial.
• Enhanced strength on the composite enclosure, with thick molding and durable threaded cable entries.
• Easy wiring through the terminal PCB board.
• NOVA V3™ switch option ensures extreme durability and high power switching capabilities.
• ASI communication protocol board .
•Integrated mounting kit for Namur actuators.
