Edited by Zak Khan || It may seem as though linear encoders and rotary encoders have strictly defined (and maybe even mutually exclusive) applications. Prevailing logic is that linear encoders track linear motion and rotary encoders track rotating shafts — but this isn’t always the case. Some motion designs can use linear or rotary encoders, […]

How to program smart encoders and their diagnostics
Edited by Zak Khan || Smart encoders are encoders that contain hardware and associated software that let them dynamically change settings such as resolution and output circuit type. So one model of smart encoder can often replace many different models of traditional encoders. Read the related encoder FAQ: Why do some encoders have embedded microprocessors for signal […]
New rotary encoders for safety-critical systems from POSITAL
POSITAL has expanded its family of IXARC absolute rotary encoders to include models explicitly designed for use in safety-critical motion control systems. The new encoders feature redundant measurement elements and are certified to Safety Integrity Level 2 (SIL 2) and Performance Level d (PL d). They feature a PROFINET communications interface and support the PROFIsafe […]
Lightweight modular rotary encoder for machine designers
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 […]
