High precision - thanks to the optical measuring principle
Product News Thursday, October 27, 2016: Electro Mechanical Systems Limited
FAULHABER expands its portfolio with the high-precision IER3 and IERS3 encoders. Both encoders deliver 2 channel quadrature signals and an additional index signal. The encoders are highly precise thanks to the optical measuring principle. Regarding accuracy and signal quality they stand out compared to encoders with other measuring principles. A FAULHABER DC-micromotor or brushless DC-Servomotor can be positioned with a typical accuracy of 0.1° – 0.3° with the IER3 and IERS3. The encoders are therefore the ideal solution for high-precision positioning applications. The encoders can be combined with the graphite-commutated FAULHABER DC-micromotor of series CXR and CR starting with a diameter of 22 mm and with the brushless DC-servomotors of series BX4 and BP4.
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 very little 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 Driver 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 very high control dynamics and very 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 demanding positioning applications such as those in medical technology, laboratory automation, measuring technology or in optical systems due to very high accuracy and repeatability. The optical encoders can also be used in automation technology, for example, in semiconductor manufacturing or in 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 image processing.
