MAGNETIC attractionforce makes thin plates ex and touch each other causing an electrical plate s surface has been treated with a special material particularly suitablefor low current or high inductive circuits.

2 MAGNETIC SENSORS compared to tradi-tional mechanical switches have the following advantage:- Contacts are well protected against dust, oxidization and corrosion thanks tothe hermetic glass bulb and inerted gas; contacts are activated by means of amagnetic eld rather than mechanical Special surface treatment of contacts assures in normal electrical conditionsmany of working Maintenance free, reduce reed MAGNETIC switches o er many electrical and mechanical characteristicstogether with various output When in normally open ( ) mode the open reed contact closes as are supplied with two When in the normally closed position ( ) the Redd contact, in rest position,opens as magnet gets closer. These models are created by using exchangingreed contacts in which output has been are supplied withtwo When in the exchangeable (S) mode both functions are made available by means ofa single galss bulb.

3 Placing the magnet close to orfar from the reed switch activates the two di e-rent positions. They are supplied with three wires,one is in common, one is and one is TYPICAL REED CONTACT PROTECTIONSThe lifespan of a MAGNETIC sensor , at low values oftension and current, depends on the mechanicalcharacteristics of the at high tension and current values it s thecharacteristics of the load that in uences the life-span instead.

D indicates the sensing distance, C indicates the value, under this value the contact switches off (see example of funtionig). Data shown on the abovetable have an approximate value, referred to appliances which are not ferromagnetic and with magnet for fron-tal working. The MAGNETIC SENSORS can also work with a lateral magnet. In case of setting-up on ferrous surfaceswhich scatter the MAGNETIC flux, it is necessary to interpose suitable spacers made of non- MAGNETIC DIAGRAMSS tandard versionVersion on requestBROWNBLUEBLUEBLACKBROWNBROWNBLUEV 2001501005000 0,2 0,4 0,6 0,8 1V50040030020010000 0,5 1 1,5 2 2,5 3 IISWITCHING POWER DIAGRAMSV oltage (V), switching current (I) and max.
