RSF50 series are compact vertically mounted devices with a single switch point.  Mounting is either from the top or bottom of a tank from the inside, so requires access to the inside of the tank. 

Typical applications include vending machines, printing systems and chemical dosing equipment. 

These can be manufactured in a variety of plastics, with a choice of gasket materials, to suit most commonly used liquids.

Custom versions can be made for particular applications.  Please contact Cynergy3 with your requirements. 

The switch action may be reversed by removing the float, inverting it, then refitting to the stem. 

All the standard types are also available with 1/8”NPT tapered thread mounting (The last letter of the part number is replaced with 1/8.)
