Product Overview
The Sensata RSF50 Series offers compact, vertically mounted float switches with a single switch point. Designed for internal mounting from the top or bottom of a tank, these devices require access to the inside of the tank. Typical applications include vending machines, printing systems, and chemical dosing equipment. The RSF50 series is available in a variety of plastic materials and gasket options to suit commonly used liquids. The switch action can be reversed by inverting the float. Mounting thread options include M12 x 1.75 or 1/8NPT. Variants are available with UL recognition, and some are WRAS and NSF approved.
