HEIDENHAIN is meeting the market demand for high-speed, high-resolution modular rotary encoders for motion feedback with the launch of the ERO 2000 series encoder. The encoders’ special properties are that they have a very compact design, excellent signal quality and therefore high interpolation rates, as well as excellent thermal position stability. The introduction of this […]

FAQ: What are traditional and newer multi-turn measuring systems for encoders?
Edited by Zak Khan || Multi-turn measuring encoders are absolute encoders that can count multiple turns. Three main technologies enable such encoder design — batteries, gearing, and self-powering setups. Batteries and gears are traditional implementations of multi-turn technology; self-powering setups are newer. Batteries: Simple but incur replacement costs Batteries maintain power supply even during machine […]
Ways to wire an absolute encoder into a motion system
Absolute encoders are traditionally wired in one of three ways: in parallel, with a serial interface, or over a bus. The serial and bus interfaces have multiple protocols or standards, some of which are open-source, while others are proprietary to specific manufacturers. When considering how to wire an absolute encoder, the required resolution, level of […]
FAQ: How do magnetic encoders work?
Encoders, whether rotary or linear, absolute or incremental, typically use one of two measuring principles—optical or magnetic. While optical encoders were, in the past, the primary choice for high resolution applications, improvements in magnetic encoder technology now allow them to achieve resolutions down to one micron, competing with optical technology in many applications. Magnetic technology […]
What are capacitive encoders and where are they suitable?
Two types of encoders dominate the general industrial market—optical and magnetic. But capacitive encoders, a relatively new introduction, offer resolution comparable to optical devices, with the ruggedness of magnetic encoders. Currently, there are only a handful of vendors for capacitive encoders, but their suitability for applications requiring high precision and durability make them a good […]
Determining pulses per revolution for an encoder application
Incremental encoders determine rotary position by generating a specific number of pulses per revolution (PPR) and counting those pulses as the encoder spins. The PPR rating indicates resolution, and is typically the most important factor when selecting an incremental encoder. But how do you determine what PPR is needed for a specific application? Fortunately, establishing the required […]
