FAULHABER IERF3 L incremental encoder

Click2Contact

The FAULHABER IERF3 L incremental encoder is designed to provide precision in space-constrained applications. Built on an advanced optical sensing platform, the IERF3 L delivers optimised resolution, 0.1° positioning accuracy and 0.007° repeatability — making it suitable for high-precision motion control.

Available in 22, 32 and 42 mm diameters, the encoder is matched to FAULHABER’s BXT series of brushless flat DC micromotors. It features a built-in line driver for noise-resistant, long-distance signal transmission, and can be optionally paired with a brake for added control.

The encoder is built for demanding environments like metrology, robotics, microscopy and semiconductor manufacturing, where precision and reliability are paramount. As an optical encoder, it is also immune to magnetic interference — an added advantage in sensitive installations.

The IERF3 L incremental encoder is designed for applications that call for tight tolerances and optimised feedback.
