These values are maximum values and they can not be used at the same �me.When you need to use the pressure switch in agressive chemicals or fluids please contact with us. You must s�ct to rules of clearence standarts Hydraulic oils (fluids). Use filtera�on to blockingsystem errors. It is effec�ve for long working life of pressure switches. Please avoid using out of indicated values to have a long service from pressure switch.

NOTES

ENG

LP A1 pressure switch opens or closes electrical circuit depending on pressure is dropping or rising. Working Pressure, 7 bar to 600 bar, can be set by

pressure se�ng knop on the pressure switch. When you turn the se�ng knop to clockwise, pressure rises up. It works appropriately under shock and

high pressures. The pressure is se�able by pressure se�ng knop on the pressure switch. When customer system is working, pressure switch has se�able

speciality. An se�ng knob makes it interes�ngfor customer due to easy and convinient se�ng of pressure. LP A1 series pressure switches are employed

wherever compressed air, fluids, gases are used and a precisely set hystherisis is needed. The pressure switch has ver�cal stacking connec�on holes for

bo�om flange connec�on. It has moun�ng design for all axis'. They classified depending on pressure se�ng ranges.
