Woerner KFR-B LEVEL SWITCH

Technical Data - General: Technical Data - Reed Contacts: For the detection of liquides levels in reservoirs. In the lower end of the conductor pipe there are two Reed contacts having a difference distance of 25mm for prewarning and disconnection. The switching function is bistable. The switching functions are shown via LEDs being integrated into the receptacle. LED green = voltage supply LED yellow = pre-warning switching point L2 LED red = minimum level switching point L1 Operating pressure max: 10 bar Temperature range: 0...90 °C Mounting position: vertical ± 20 ° Material: Internal pipe D 18: CU-alloy External pipe D 60: Al-alloy Flange: Al-alloy Float: 1.4571 Sealing: Abil Protection type: IP 65 Protection class: II (protection insulated) Plug-in connection: M12x1, 4pol. Flange: Drill pattern at DIN 24557 part 2 Weight at L1 = 300: 0,45 kg Switching voltage: 18...30 VDC Switching current max.: 1A Switching power max.: 40/60 W/VA For inductive an capacitive loads, suppressor circuits shall be provided for.
