MICROMO is pleased to announce the new high precision IER3 and IERS3 optical encoders from FAULHABER. Both encoders deliver 2 channel quadrature signals and an additional index signal. The encoders are highly precise, thanks to the optical measuring principle. This measuring principle gives these encoders a strong edge in terms of accuracy and signal quality when compared to encoders with other measuring principles.","A FAULHABER micro DC motor or brushless DC servo motor can be positioned with a typical accuracy of 0.1° to 0.3° with the IER3 and IERS3, making the encoders an ideal solution for high precision positioning applications across markets.","The encoders can be combined with series CXR and CR graphite-commutated FAULHABER micro DC motors, starting with a diameter of 22 mm, and with FAULHABER series BX4 and BP4 brushless DC servo motors. The encoders and their motor combinations can also be used with the new FAULHABER MC3\/MCS motion control family.","The encoders are exceptionally compact and light in comparison to other optical encoders. The encoders are an opto-reflective system as a single-chip solution: As the LED, photodetectors, analysis unit and interpolation levels are installed in one chip, the encoders take up minimal space. The diameter compliant IER3 and IERS3 encoders are mechanically identical and compatible with the magnetic FAULHABER IE3 encoder. They lengthen the motors only from 15.5 to 18.5 mm.","Both encoders are also available with line drivers as the IER3 L and IERS3 L. The line driver generates complementary output signals and makes the transmission of data particularly resistant to electrical interference, especially in encoders with long connecting cables.","The IER3 sets the standard and provides the highest resolution for its class with a resolution of up to 10,000 lines per revolution. The encoder achieves an angular resolution of 0.009°, with the evaluation of 40,000 edges per revolution. The high resolution results in high control dynamics and precise speed control. A multitude of further resolution variants are available. The IERS3-500 provides resolutions of 250 and 500 lines per revolution.","The IER3 and IERS3 optical encoders are perfectly suited to fit demanding positioning applications, such as those in medical technology, laboratory automation, measuring technology or in optical systems due to high accuracy and repeatability requirements. The optical encoders can also be used in automation technology, semiconductor manufacturing or robotics.","As the optical encoders are resistant to strong magnetic interferences, they are also well-suited for applications with magnetic interferences such as in tomography or medical image scanning and processing.
