Used for the liquid monitoring and control in tanks, the M-series magnetic level switches are specifically manufactured to customer specifications. The float switches feature a hermetically sealed contact located within the guide tube. The float sliding on the tube contains a ring magnet that activates the sealed contact in a non-contacting fashion. The sealed contacts are available as SPST (N/O or N/C) or SPDT (N/O + N/C). The float sliding up and down on the guide tube is the only moving part. For more details, a datasheet is available at http://koboldusa.com/sites/default/files/product_files/M_datasheet.pdf
