Series MMA-4050155-AX

Precision in a Stainless Steel Body

The MMA-4050155-AX series includes large-volume stainless steel magnetic floats (SUS304 and SUS316L), specifically developed for use in aggressive media and under demanding temperature conditions.
Thanks to an axially magnetized ferrite core, they enable reliable, non-contact activation of reed switches – ideal for level detection in industrial applications.
