MICROMO Announces the Launch of IER3 and IERS3 Optical Encoders

The IER3 and the IERS3 have been released by MICROMO.

MICROMO has released two high-precision optical encoders, the IER3 and IERS3.

Both encoders deliver two channel quadrature signals and an index signal. They are precise thanks to the unique optical measuring principle, which gives them a strong edge in accuracy and signal quality when compared to encoders with other measuring principles.

A FAULHABER direct current (DC) micro 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 a wide range of high precision positioning applications across various markets.

The encoders can be combined with series CXR and CR graphite-commutated FAULHABER DC micro motors, starting with a diameter of 22mm, 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 MCS/MC3 motion control family.

Exceptionally compact and lightweight, the encoders are an opto-reflective system as a single-chip solution. As the LED photo-detectors, analysis unit and interpolation levels are installed in one chip, the encoders take up very little space.

Diameter-compliant IER3 and IERS3 encoders are mechanically identical and compatible with the magnetic FAULHABER IE3 encoder. They lengthen the motors only from 15.5mm-18.5mm. 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. This high resolution results in high-control dynamics and precise speed control. In addition, 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 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 image processing.
