## **| 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 1/8”NPT mounting threads. 

## Features 

- Compact design 

- Available in Nylon, Polypropylene, PPS & PVDF 

- 3VA, 25VA & 100VA versions 

- Many variants are UL recognised components File No. E171218 

- WRAS and NSF approved versions 

- 1/8” NPT and M12 thread options
