Con­tact­less in­cre­men­tal en­coder

The con­tact­less and bear­ing-less ro­tary in­cre­men­tal EMI 22 and EMI 55 en­coder se­ries with mag­netic tech­nol­ogy in­te­grated are the ideal so­lu­tion for harsh en­vi­ron­ment ap­pli­ca­tions and for in­dus­trial sys­tems that re­quire high speed and re­sis­tance (i.e. iron and steel, glass, ce­ram­ics, mar­ble, wood and textile pro­cess­ing in­dus­tries) and, at the same time, an ex­cel­lent re­li­a­bil­ity and a high en­clo­sure rat­ing from dust and liq­uids. The key fea­ture of EMI 22 and EMI 55 se­ries is the in­te­gra­tion of the mag­netic prin­ci­ple also to the fix­ing sys­tem of the en­coder to the mo­tor shaft: thanks to the ap­pli­ca­tion of a mag­net on the shaft, there is no phys­i­cal cou­pling be­tween the de­vice and the ma­chine, which im­plies sev­eral ben­e­fits: • No wear and long-last­ing life of

the en­coder. • Ex­tremely sturdy and com­pact

de­sign. • High ro­ta­tion speed (10.000 rpm); • Ex­cel­lent re­sis­tance to vi­bra­tions (10 G, 10 ... 2000 Hz) and to me­chan­i­cal load­ing. • Wide range of op­er­at­ing tem­per­a­ture (from -40°C to +125°C max). • Very easy mount­ing.
