Woerner KFH-KFS level switch
BRAND : Woerner
Aplication:
Function:
Registration of liquid levels in reservoirs.
One or max two Reed contacts are integrally cast in a sliding tube. A float with a permanent solenoid moves along the sliding tube
to match the filling level. When the solenoid
approaches the Reed contact the latter is
operated without contact.
In the respective switching positions the
rising of the float is prevented by means of
safety rings.
Switching functions see order designations.
Plug-in connection 4pol. M12x1 for
sensors.
One or two switching point for level
monitoring
Flange G1/2 or M20x1,5
Tecnical data - general:
Technical Data - Reed Contacts:
Operating pressure max.: 1 bar
Temperature range: 0...90 °C
Mounting position: vertical ± 10 °
Material:
Tube version M: copper alloy
Tube version V: 1.4301
Float: polyurethane
Flange: aluminium alloy
O-ring-seal: NBR
Protection type: IP 65
Protection class: II (protection insulated)
Plug-in connection: M12x1; 4pol
Weight L=300: 0,16 kg
Switching voltage max.: 30 VDC
Switching current max.: 0,25A
Switching capacity max.: 3 W
For inductive and capacitive loads, suppressor circuits shall be provided for.
(Diode, RC element, varistor)
