Limit switches are used to control, monitor and view the position of the valve or to activate other system components.

There are different versions of on/off limit switches in the market. The most common are based on the principle of echanical switches, proximity sensors or potentiometers.

SED has designed and engineered a contact-free limit switch with magnet field measurement technology. Apart from lifetime and among other features the advanceddesign allows also a more reliable sealing method.

Features
• For single and double acting valve control functions
• Suitable for linear and rotary actuators
• Linear stroke measurement of 3-45 mm
• Indicates two or three positions
• Backlash free stroke transmission
• Short circuit proof
• M12, 5 pin A-coded connection

Advantages
• Contact-Free magnetic measuring design
• Colored LED light feedback of valve position visible for 360°
• Compact and robust design
• Hermetically sealed
• Easy mounting without additional adapter kits
• Mounts to all standard valves up to DN100
• 360° adjustable mounting position
• Initial programming by light or 24V Signal (5th pin)
• Set point protection
• High switching current
• High chemical resistance
