Flow Switch FW1-...GM

Référence: FW1-008..025GM

Flow Switch FW1-...GM

● Economical design
● High switching power
● Insensitive to dirt

Characteristics :

Mechanical flow switch, for fluid media, with spring-supported
piston and magnetic triggering of a reed switch. Robust
construction in brass and POM.

Handling and Operation
Note
● Include straight calming section of 5 x DN in inlet and outlet
● Include a filter if the media are dirty (use magnetic filter for
ferritic components).
● 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.
Adjustment
Loosen screw slightly, push the switching head into the desired
position,
