RSF50 SERIES COMPACT INTERNAL FITTING VERTICAL 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. The switch action may be reversed by removing the float, inverting it, then refitting to the stem. Available with M12 x 1.75 or 1/8NPT mounting threads. Features Compact design Available in Nylon, Polypropylene, PPS & PVDF 25VA & 100VA versions Many variants are UL recognised components File No. E171218 WRAS and NSF approved versions 1/8 NPT and M12 thread options SPECIFICATIONS Technical RSF53 RSF54 RSF58 RSF56 RSF57 Nylon Polypropylene Polypropylene Polyphenylene Polyvinylidene Material WRAS approved UL approved Sulphide (PPS) Fluoride (PVDF) Black Opaque White Grey Green Colour -20/+75 -20/+100 -20/+100 -10/+120* -10/+105 Temp.
