The IERF3 L incremental encoder has a positioning accuracy of 0.1° and repeatability of 0.007°. It is available in three sizes and is optimally matched to the brushless flat DC micromotors of the BXT family. The device is available in diameters of 22 mm, 32 mm and 42 mm and can also be combined with a brake if required. The encoder is equipped with a line driver as standard, which ensures complementary output signals and reliable data transmission. As an optical encoder, it is also resistant to magnetic interference fields.
