Product Overview
The RSF80 series offers compact external float switches designed for reliable level monitoring in tanks. Featuring a NPT external mount, these switches can be installed without requiring internal tank access, making them ideal for applications such as diesel generators, hydraulic oil, and gearbox oil levels. Manufactured from a range of plastics including Nylon, Polypropylene, PPS, and PVDF, they are suitable for various commonly used liquids. The switch action (make on rise or make on fall) can be easily configured by rotating the unit 180. Available with flying leads or M12 circular connector sockets, with compatible cables offered separately. WRAS and NSF approved versions are available, and many variants are UL recognized components.
