Dual-Magnet Float Switch Model NGS... Method of Operation As the level rises and falls the inclination of the float is changed causing a permanent magnet in the float to be deflected which in turn repels a rotatable opposing magnet. This forced snap-action-contact effect operates a microswitch with a plunger. Even very small changes in level can be detected in this way. Special Advantages • Secure and wear-free sensitive switching by repelling magnets • High switch capacity up to 10 A with microswitch • Very rugged for tough environments • No regular maintenance necessary • Medium...

Fixed switch hysteresis, side installation L =  202-521protrusion length dependant on required switch L =202-521 abhängig von Armlänge differential length Switching data model NGS-21... LK = linkage length L = protrusion length Lmax = total swing X1 = high switch point X2 = low switch point Note: The data apply to water at 20 °C, tolerance ±5 mm Adjustable hysteresis, installation from above (NGS-23) The hysteresis can be adjusted by positioning the rings on the rod. By positioning the counterweight the different rod lengths can be compensated. No...
