IP 67 DIN40050: IP69K Pressure medium -40º C to 100º C temperature Ambient temperature -40º C to 85º C Electric spec. 28 VDC: 3A inductive load, 5A resistive load 250 VAC: 5A Pressure range between 2 and 350 bar can be ordered Medium mineral- or synthetic based hydraulic fluids (with std. NBR seal) Installation Observe! Fixed setting. Will break at attempt to adjust Features • High pressure range • Withstands high pressure water spraying • High reliability • Tested to over 1x106 pressure cycles • High bursting pressure • Built in microswitch with silver contacts • Piston type Performance Symbols PRODUCT DESCRIPTION The pressure switch type KT is a pressure controlled electric switch, consisting of a piston activated microswitch with silver contacts. The pressure switch is factory pre-set to ordered pressure and not possible to re-adjust. Operation KT 32 disconnects the power when pressure rises (NC). KT 33 connects when pressure rises (NO). KT 34 switching when pressure rises/falls.
