POSITAL Motor Feedback Kit Encoders — now with open-source BiSS interface
Rotary encoder specialist POSITAL has expanded its interface offerings for its magnetic Kit Encoders with support for the nonproprietary open-source BiSS Line communication protocol. This enables the practical implementation of single-cable technology, which is becoming increasingly popular with motor and robot manufacturers. POSITAL’s easy-to-install motor feedback kits, which feature 17-bit electronic resolution, bridge the gap […]
What is modulo positioning?
In motion control, there are typically two types of positioning that can be used for a linear or rotary axis: relative, in which each position is based on a previous position, regardless of the actual position of the axis; or absolute, in which each position is referenced to a home, or zero, point. Axes that […]
Absolute, high-resolution motor feedback sensor from SIKO
The MSAC501 absolute sensor from SIKO offers a truly absolute solution for measuring motor feedback. The exact sensor position is available immediately after a current interruption so additional reference or mechanical activity is not necessary. The MSAC501 sensor works with standardized SSI or RS485 interfaces. An optional LD output for digital signal output is also […]

This multi-turn hollow-bore absolute encoder is designed for harsh factory and plant floor environments … and is especially suited to applications where you need an encoder with the capability of output even in power-off scenarios. The Model MA58H has […]
CANopen interface on precision magnetic encoders from POSITAL
POSITAL’s IXARC high-precision magnetic absolute rotary encoders are now available with CANopen interfaces. These new interface option is in addition to the previously announced SSI, EtherNet/IP, EtherCat, Powerlink, Profbus DP and Profinet interfaces. Together, this range of interface choices makes the rugged and compact IXARC encoders one of the most versatile devices of its type […]
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 […]
