Home Products Sensors Liquid Level Sensors and Floats B12450 Series Magnetic Float

B12450 Series Magnetic Float

The B12450 Series is a compact magnetic float designed for integration within bottle assemblies for fluid level sensing. Operating with a minimum fluid specific gravity of 0.79, it is optimized for use with the R11774 and R12180 Series Liquid Level Sensors. Its small form factor and compatibility with molded plastic containers make it ideal for automotive, appliance, and industrial applications requiring precise and reliable float-based actuation.

Constructed for seamless operation within fluid reservoirs, the B12450 Series enables magnetic actuation without direct contact, ensuring long-term durability and consistent performance.
