Encoders feature 27-mm long housing for tight spaces
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 […]
Beckhoff Automation takes the gold in 2021 LEAP Awards Motion Control category
The winners of the 2021 LEAP Awards (Leadership in Engineering Achievement Program) were announced today in a digital ceremony, with products across 12 categories, including Motion Control. Critical to LEAP’s success is the involvement of the engineering community. The Design World editorial team assembled a top-notch independent judging panel, comprised of a cross-section of OEM […]
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 […]
POSITAL precision magnetic encoders now with BiSS-C communications interface
POSITAL’s IXARC high-precision magnetic absolute rotary encoders will be available with a BiSS-C interface. Encoders with this interface are ideal for commutation and position feedback on brushless dc servo motors and are also a good fit for motion control applications, such as medical equipment. They feature robust design, 17-bit resolution and good dynamic response (up […]
New spring-loaded pivot arm for wheel-encoder assemblies
POSITAL has introduced a new spring-loaded pivot arm mounting system for wheel-encoder assemblies. Like earlier spring-loaded mounting brackets, this device is designed to minimize slippage by maintaining a steady contact pressure between the wheel and the moving surface. However, the pivot arm can accommodate larger lateral movements of the moving surface. Spring tension can be […]
Programmability is a key encoder design trend
Encoders are central to motion control applications, providing feedback in order to increase system accuracy and reliability. As other components in motion systems evolve, encoder manufacturers are making sure that their offerings keep pace with these broader technological changes. For instance, the rise in high-performance networks for motion control is in part driven by the […]
Multi-turn encoders for miniature motors require no battery backup
POSITAL’s new 22-mm multiturn kit encoders are high-precision multiturn absolute position feedback devices for miniature motors and drives. While motion feedback devices for small motors have previously been limited to single-turn or incremental encoders, the new compact kit encoders from POSITAL now provide full multiturn measurement capabilities – without any need for backup batteries. The […]
Feedback on stepper motors for better positioning and holding (and less ringing)
Feedback-equipped stepper motors are not a complete substitute for servomotors, but they can provide a reliable alternative for many real-world applications. These motion-design solutions improve machine performance without breaking the bank. By Jim Stevens • Product Specialist | POSITAL Inc. Stepper motors are a top choice for many motion and position control applications. They’re available […]
Wiegand sensors offer proximity sensing with extra powers
Wiegand sensors are tiny devices that use variations in an external magnetic field to generate electrical signals and energy. They have unique properties that make them a useful option for many proximity sensing systems. Wiegand sensors are built around small sections of Wiegand wire, a specially prepared ferromagnetic alloy that has a unique physical property. […]
