The new incremental encoder IERF3 L from FAULHABER is designed for high-precision positioning applications in confined spaces

Miniature drive systems, servo components, and drive electronics provider Faulhaber said it is expanding its product range with the new, ultra-precise incremental encoder, IERF3 L.

The company said that thanks to the optical measuring principle and state-of-the-art chip technology, the device offers high resolution, excellent repeatability and outstanding signal quality.

Encoder targeted for high-precision positioning applications

Faulhaber said that in typical applications, the positioning accuracy is 0.1° and the repeatability is 0.007°. The company said that this makes its new encoder the ideal offering for high-precision positioning applications in confined spaces.

The IERF3 L is available in three sizes and Faulhaber said it 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 (especially with long connection cables).

Thanks to its very high positioning accuracy and repeatability, Faulhaber said the encoder is ideally suited for demanding positioning applications, such as in metrology or in optical systems including lasers, microscopes and telescopes.

The IERF3 L can also be used in automation technology, such as semiconductor production or robotics. As an optical encoder, it is also resistant to magnetic interference fields.
