Magnetic Encoders

Targeted for use in harsh and dirty environments, these 30 and 40-mm-diameter compact sensors fit into space-restricted applications.

The EcoMag 30 and EcoMag 40 are incremental encoders that offer resolutions from 2 to 1,024 ppr. Their absolute counterparts, the MagRes 30 and MagRes 40, provide single-turn resolutions up to 10 bits with SSI output. Maximum rotational speed for all sensors is 12,000 rpm. The 30-mm sensors have shaft diameters of 5 mm, while the 40-mm hollow-shaft sensor accepts shaft diameters up to 12 mm. The magnetic sensors offer high shock and vibration resistance compared to optical sensors.
