LFS-03 can be is applied to detection positive or negative pressure. It can be used as a gauge or differential pressure switch with almost no hysteresis. If 2 switch points are required, 2 pressure switches with different calibrations should be employed. The method of fixing the tab terminals to the switch body does not allow for absolute air sealing. The switch is therefore not recommended for applications where static vacuum has to be maintained. However, special models with additional pressure spring which allow for the vacuum to be connected to the pressure inlet side are available on request.Model LFS-03 Electrical Function 1 pole NO1 pole NCSwitch Rating 1 pole NO:2.5(0.5) A 250V~1E41 A 250 V~5E4(max 800 mbar)20 mA 250 V~5E4(max 800 mbar)1 Pole NC:2.5(0.5) A 250V~1E40.5 A 250 V~5E4(max 800 mbar)20 mA 250 V~5E4Temperature Ambient: -10 to +85Electrical Connections Tab terminals 6.4 x 0.8 mmTab terminals 4.8 x 0.8 mm(1 pole NO only)Pressure RangePressure: +15 to +2500
