MICROMO Launches New IER3 AND IERS3 Optical Encoders from FAULHABER

A New Standard for High Precision

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
unique 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 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 markets.
The encoders can be combined with series CXR and CR graphite-commutated
FAULHABER DC micro 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 MCS/MC3 motion control family.
The encoders are exceptionally compact and lightweight 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 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 image processing.

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
