<!-- ABOUT THE ENCODERS -->
# About the Encoders
LENZ Encoders are non-contact bearingless absolute angle encoders. Two printed circuit board design is perfect to match wide variety of control and measurements applications with limited space. Precise position data up to 22 bits and reliable fast feedback in harsh environments.

LENZ encoders are inductive position sensors based on the physical principles of electromagnetic induction. Our encoders combine easy installation, low integration cost, high accuracy, stability over time, are extremely robust.

LENZ encoders are insensitive to electromagnetic fields, permanent magnets, power lines, parasitic capacitance, metallic parts and electrical noises.

# Tests Results

## Maximum Operating Speed of the Encoders

IRS-I34 encoders showed ability to provide stable output at the speed up to 38000 RPM. 
* One can dive into [output data of IRS-I34](https://github.com/lenzencoders/BISS-C/blob/main/TEST/LENZ_IRS_34U2S1-17_max_speed_test_38krpm.zip).
* Also we have a [📹 Video](https://www.youtube.com/watch?v=S2KUlJbIPas) of the speed test.
