M7700 1/2” x 1/2” NPT Side-Mounted PBT Float Switch
Side-Mounted Plastic Liquid Level Float Switch
The M7700 side-mounted liquid level switch has a PBT
stem and a PBT float. PBT is a strong plastic that features
excellent structural integrity. It is best used where
temperature resistance and permeability are not factors
such as fuel and hydraulic systems up to 130°C. This switch is
ideal for single point float switch level detection when needing
to sense high or low fluid levels in tank applications.
The M7700 is not recommended for use in hot water or soap water applications above 65°C.
