Encoder REMA

Single turn magnetic encoders

The single turn absolute encoders series EMA operate according to the magnetic principle: the rotation of a permanent magnet placed on the encoder shaft generates a sinusoidal magnetic field on 360 degrees. The electronic circuitry provides as output the absolute position.

EMA encoders offer an excellent resistance to vibrations and shocks, and high protection against environmental agents, characteristics which make them fit for applications in industrial environments with presence of oil or dust, or on plants which must be water/solvent-cleaned.

A further, but not less important, advantage of EMA encoders is their excellent price/performance relation, which allow their use also in those cases where containing costs is a basic requirement.

The absolute magnetic encoders series EMA have a resolution ranging between 4 and 13 bit, binary code, SSI serial output and suppy 5/24, 10/24 or 5/24 Vdc. Many different mechanical versions are at disposal: round flanged, servo-coupling, standard flange RE0444, square flanged, hollow shaft encoders, with plastic or metal case (series REMA).
