Baumer Electric (Southington, CT) released four magnetic encoders for harsh or contaminated environments. The devices come in diameters of 30 and 40 mm. The EcoMag 30 and EcoMag 40 are incremental encoders, offering resolution from 2 – 1,024 ppr. Their absolute counterparts, the MagRes 30 and MagRes 40, provide single-turn resolution up to 10 bits and SSI output. Maximum rotational speed for the sensors is 12,000 rpm. The 30 mm sensors have shaft diameters of 5 mm; the 40 mm hollow shaft sensor accepts shaft diameters of 12 mm. Both models are resistant to high shock and vibration.
