Non-mediumcontact materials Weight Installation location
plug DIN 43650-A / ISO 4400 Optionally for round plug connector M12x1, 4-pole
Brass construction:
Stainless steel CW614N nickelled, construction: 1.4571, CW614N, 1.4310, 1.4404, 1.4310, hard
hard ferrite, NBR ferrite PTFE-coated, FKM PA, CW614N, NBR 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 ● viscosity stabilized
Viscosity compensated type HD2K Switching Optionally range Display range
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.
