Mechanical flow switch, for fluid media, with magnetic triggering of a reed switch. Plastic housing with integrated filter.

● Adjusted switching value
● Integrated filter
● High switching power
● Optional flow limiter in the outlet piece

Handling and operation

● Include straight calming section of 5 x DN in inlet and outlet
● It must be ensured that the values given for voltage, current,
and power are not exceeded.
● When switch on, a load must be connected in series.
● The electrical details apply to ohmic loads. Capacitive,
inductive and lamp loads must be operated using a protective circuit.
