MMA-5252155-AX series

Precision in a stainless steel housing

The MMA-5252155-AX series comprises large-volume stainless steel (SUS304 and SUS316L) magnetic floats, specifically developed for use in aggressive media and under demanding temperature conditions.
Thanks to an axially magnetized ferrite core, they enable reliable, contactless activation of reed switches—ideal for level detection in industrial applications.
