Woerner KFR-B LEVEL SWITCH KFR-B Woerner KFR-B LEVEL SWITCH

Technical Data - General:Technical Data - Reed Contacts:For the detection of liquides levels inreservoirs.In the lower end of the conductor pipethere are two Reed contacts having adifference distance of 25mm for prewarning and disconnection. The switchingfunction is bistable.The switching functions are shown viaLEDs being integrated into the receptacle.LED green = voltage supplyLED yellow = pre-warningswitching point L2LED red = minimum levelswitching point L1Operating pressure max: 10 barTemperature range: 0...90 °CMounting position: vertical ± 20 °Material:Internal pipe D 18: CU-alloyExternal pipe D 60: Al-alloyFlange: Al-alloyFloat: 1.4571Sealing: AbilProtection type: IP 65Protection class: II (protection insulated)Plug-in connection: M12x1, 4pol.Flange: Drill pattern at DIN 24557 part 2Weight at L1 = 300: 0,45 kgSwitching voltage: 18...30 VDCSwitching current max.: 1ASwitching power max.: 40/60 W/VAFor inductive an capacitive loads, suppressor circuits shall be provided for.(Diode, RC element, varistor)
