● High switching power
● Compact design

Characteristics :

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

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
If it is necessary to set the switching value,
the switching head can be adjusted
lengthways.
