Absolute Encoders
IXARC encoders from POSITAL FRABA for hazardous locations
IXARC rotary encoders from POSITAL FRABA are dedicated to Zones 2 & 22 — ATEX compliant and operate safely in atmospheres with potentially dangerous levels of explosive gases or dust (3G and 3D). These devices can be delivered with either programmable incremental or absolute output. For Group II Applications Dedicated to Zone 2 & 22 Provide Absolute […]
Kit encoders using magnetic operation — now for closed-loop position and speed feedback
Christian Fell • POSITAL FRABA | Magnetic rotary-encoder technology is a staple for incremental and absolute motion tracking. Now some manufacturers are offering new encoder geometries based on the technology to give OEMs and machine builders flexibility in the way they incorporate measurement capabilities into products. The encoders don’t require the extreme cleanliness and assembly precision […]
FAQ: How do digital encoders simplify setup and zeroing?
In a recent Design World video, my esteemed colleague Miles Budimir and I got to assemble and zero an AMT31 commutation encoder from CUI Inc. As we’ve covered in other editorial, capacitive technology can outperform optical technology. Used for years in digital calipers and to measure rotational movement, capacitive technology in encoders replaces optical disks with a printed circuit-board rotor […]
Netzer DS-25 17-bit resolution absolute encoder
The DS-25 is a member of the DS series of Electric Encoders, based on Netzer Precision proprietary technology. These encoders offer many advantages, some unparalleled: 17 bit resolution and accuracy to better than 0.025° Analog Sin/Cos,Digital SSi,BiSS-C output options Lightweight miniature absolute rotary encoder Hollow floating shaft and no bearing or other contact High precision […]
What kinds of encoder features boost ruggedness? Solid-state electronics, maybe?
Digital technology boosts the reliability of rotary-encoder designs. By Jeff Smoot, VP of Application Engineering & Motion Control, CUI Inc. Encoder applications are all around us, from BattleBots to the Mars Rover, large construction vehicles to semiconductor manufacturing equipment, and in numerous medical and military applications. In short, wherever there is motion, an encoder is […]
Bringing production lines up to speed with automation — including encoders
By Christian Fell, POSITAL-FRABA Inc. | The automotive industry is a place of constant change as car-makers work hard to respond to evolving customer preferences and new regulatory requirements. Not only must car makers constantly refresh their models lines, they must also be constantly upgrading their production facilities to optimize productivity and product quality. When a […]
Direct drive rotary servo tables fitted with absolute encoders
IntelLiDrives now offers a new series of low-profile PSR300MHS-ABS tables — large-center-aperture direct-drive rotary servo tables fitted with absolute encoders. Benefits of absolute encoders and direct drives in rotary servo tables The major advantage of an absolute encoder over an incremental encoder is that the absolute encoders keep track of position at all times —and provides position as soon as the system gets power. […]
FAQ: How do I pick between rotary and linear encoders?
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 […]
