Floatless Level Switch (Compact, Plug-in Type) 61F-LS

Normal / High functionality type

 

• Compact form allows space-saving design

• Increase in number of models in which wiring of up to 4 km is possible

• Easy to replace during maintenance due to compatibility with the 61F-GP-N series

• Dip switches allow switching of the response speed and operation sensitivity

 

DC power supply type

 

• Battery for use in locations without AC power supply

• Adjustable sensitivity, with an operating resistance range of 0 to 100 kΩ, allows use for a wide variety of liquids

• NPN output type available

• Allows switching and selection of water supply and drainag
