POSITAL has added new models of its IXARC rotary encoders with housings that are only 27 mm long. This reduced length, combined with a diameter of only 36 mm, means that these super-compact devices are ideal for tight spaces. The radial cable entry and shaft seal have protection ratings of IP65, ensuring reliable operations under […]

Celera Motion debuts ultra-lightweight inductive angle encoder
Celera Motion has released an innovative new device for precise angle measurement; a compact, ultra-lightweight inductive angle encoder, ideal for a variety of surgical, medical and industrial robotics. The new IncOder CORE is a non-contact device featuring the robust and reliable position sensing technology of IncOder — all fully contained in a stacked printed circuit board […]
How do Hall effect sensors work and where are they used in motion applications?
The Hall effect is an outcome of the Lorentz force at work. When a thin conductor (or semiconductor) has a steady flow of current running through it and a magnet is placed so that its magnetic field runs perpendicular to this current, the magnetic field of the current reacts to the magnetic field of the […]
What to consider when choosing a rotary encoder
Controlled servo drives are used in many areas of automation technology, converting, printing, handling, and robotics, including production machines and machine tools. The selection of a rotary encoder or encoder technology for use within the system depends on the accuracy requirements of the application and whether the application will use position control, velocity control, or both. […]
Encoder provides both motor feedback and position measurement in one
Designed to fulfill two critical needs via a single component in high accuracy robots, HEIDENHAIN introduces the innovative KCI 12O Dplus rotary encoder. This new unique absolute encoder provides both reliable feedback to a robot’s motor and accurate position measurement to its controller to enable safe and accurate motion. Extremely compact, the KCI 120 Dplus […]
When is dither helpful in motion control systems?
Dither is one of several terms used to describe small, rapid, back-and-forth movements of an object. Depending on the context, when the term “dither” is used in motion control systems, it can refer to purposeful, commanded movements or to unintended, unwanted motion. In some motion systems, dither is purposely induced to reduce the effects of […]
POSITAL upgrades PROFINET interface for absolute rotary encoders
POSITAL has upgraded the performance of the PROFINET communications interface for their IXARC series of absolute encoders. The speed of the interface has been increased, reducing cycle time by a factor of eight. In addition, new capabilities have been added, including acceleration monitoring and over-temperature warnings. Output from the encoders can be scaled (amplified or […]
What type of encoder can measure speed?
Encoders and resolvers are used to track the angular or linear position of an object, such as a motor shaft (angular measurement) or a linear actuator (linear measurement). And with the addition of a clock signal, encoders and resolvers can also be used to measure the speed of the object. A resolver uses a rotor with […]
What’s the difference between radial and axial ring encoders?
A traditional rotary encoder measures the position or speed of a rotating shaft, with mounting via a coupling or a hollow bore that allows the encoder to fit over the shaft. But not all rotating components have a shaft to which the encoder can mount. For example, direct-drive rotary motors — also known as torque motors, […]
Quantum Devices QML35 rotary encoder replaces RENCO product
Users of now-obsolete RENCO model turn to Quantum Devices. Since being absorbed by Heidenhain, RENCO has eliminated many of their encoder products. The most recent model discontinued is their RCML15 rotary encoder, a slim and lightweight commutating encoder popular among motor designers and used in a multitude of industries. To help fill the needs of […]
