Magnetic Encoding Technology

Magnetic encoders are known for their ability to work in tough environments. In this short video, SIKO Products Inc. President Darrel Davey describes how MagLine Incremental systems work. They include a magnetic band attached to the measurement surface, a sensor, and a signal translation module that feeds to a controller. The band is manufactured with evenly-spaced north and south magnetic poles along its length. As the powered sensor moves along the path of the band, it outputs a number of pulses between each pole. These sensors can operate in both absolute and incremental modes.
