MR1K-GMK040 Flow Switch

Flow Switch MR1K
Materials medium-contact
Brass construction:
CW614N nickelled, CW614N, 1.4310, hard ferrite, NBR
Non-mediumcontact materials Weight Installation location
PA, CW614N, NBR
Stainless steel construction: 1.4571, 1.4404, 1.4310, hard ferrite PTFE-coated,

see table "Dimensions and weights" Standard: horizontal inwards flow from the
left; other installation positions are possible;
the installation position affects the switching point and range.
Ranges For switching ranges, the details in the table correspond to horizontal inwards flow and decreasing flow rate; for display ranges
they correspond to horizontal inwards flow and increasing flow rate.
● High switching power ● Compact design
Characteristics Mechanical flow switch, for fluid media, with spring-supported piston and magnetic triggering of a reed switch.
Robust construction in brass or stainless steel.
