A new and robust solution for position feedback: the ILC 3019 from HEIDENHAIN

The new HEIDENHAIN ILC 3019 is an inductive exposed linear encoder for automation applications that face strong contamination or magnetism. Reliable linear position feedback under harsh conditions is made possible by the encoder’s highly robust inductive scanning technology. 

Thanks as well to its small scanning head and wide mounting tolerances, the ILC 3019 is at home in numerous applications, including linear motors, conveyor systems, robot axes, cutting machines, automated workpiece handling solutions, and patient tables for CT scanners or MRI machines. With EnDat—a well-established digital interface—the ILC 3019 is also easy to connect to the automation controller.

New incremental rotary encoder for high machine uptime joins the LEINE LINDE 600 series

The robust and space-saving 600 series rotary encoders from LEINE LINDE were designed with inductive scanning technology for reliable operation under extreme conditions. With its new incremental variants, the 600 series now includes both absolute and incremental rotary encoders, providing a well-rounded lineup of solutions for reliable position and speed feedback in applications where machine uptime is of the essence.

The new 600 series incremental rotary encoders are resistant to humidity, dust, dirt, condensation, electromagnetic fields, and strong vibrations, ensuring consistently high signal quality even in harsh environments. Typical applications include the pulp, paper, maritime, offshore, and wind industries, along with steel mills and sawmills. 

The robust signal quality of the 600 series is augmented by a strong mechanical design: Larger bearings than are typically found on 58 mm rotary encoders, combined with a highly rugged housing, make these encoders dependable solutions for demanding industrial applications. Numerous available data interfaces facilitate installation into state-of-the-art automation systems.

The ECI and EQI rotary encoder platform: solutions for every motor feedback requirement

The modular design of the ECI and EQI inductive rotary encoders from HEIDENHAIN offers countless ways for industrial motor manufacturers to adapt motor feedback to their specific applications without needing to change the electrical or mechanical interfaces of their systems. That’s because the mechanical mounting interfaces are interchangeable within each series (i.e., the 1100 series with a 35 mm diameter or the 1300 series with a 56 mm diameter). They are also mechanically compatible with many other identically sized rotary encoders from the HEIDENHAIN product range, including the ECN/EQN 1300 optical rotary encoders. With the EnDat 3 digital interface, they even enable functionally safe applications up to SIL 3 without additional measures. 

Rounding off this product lineup at the basic end is the ECI 1116. The ECI 1116 is being launched solely as a singleturn rotary encoder with 16-bit resolution. Despite its kit design, the ECI 1116 features full compatibility with the mechanical interfaces of other 1100 series rotary encoders. It also offers functional safety up to SIL 2. Like all rotary encoders of the ECI and EQI platform, the ECI 1116 is easy to connect via the HMC2 single-cable solution, which also simplifies cabling.

Built-in vibration analysis for simplified installation without extra sensors: 
ECI 1323 Splus and EQI 1335 Splus inductive rotary encoders from HEIDENHAIN

Detecting vibration-related damage before it occurs is vital for achieving smooth production processes, perfect manufacturing results, and a long service life on high-performance and capital-intensive machinery. It’s a fast and simple way to prevent damaged products, machine damage, and other production interruptions becomes. 

The ECI 1323 Splus and EQI 1335 Splus inductive rotary encoders from HEIDENHAIN feature a built-in accelerometer along with vibration analysis, providing a convenient way to detect and analyze vibrations arising in machine components. By delivering both position feedback and vibration analysis, these encoders enable motion control and condition monitoring in a single device. As a result, the position feedback and vibration signals can be correlated, making it easy to determine the type of vibration and its precise source. These encoders also support the connection of an external temperature sensor. 

The ECI 1323 Splus and EQI 1335 Splus enable online condition monitoring, allowing users to detect and analyze machine malfunctions before they arise. As part of predictive maintenance, machine operators can optimally adapt their regular servicing intervals to actual machine strain while efficiently incorporating unplanned maintenance into their processes. All the information necessary for this is transmitted to the downstream electronics via the EnDat 3 interface. By reducing the need for additional vibration measurement sensors, the ECI 1323 Splus and EQI 1335 Splus also significantly reduce cabling and installation work.

Safer and more accurate cobots through dual and secondary encoders for collision monitoring

Dual encoders from HEIDENHAIN and secondary encoders from AMO or RSF make it possible to collect high-accuracy position feedback both directly at the robot axis motor and downstream from its gearbox, thereby increasing the robot’s accuracy. But that’s not all: dual position feedback can also be used to detect the effects of forces acting on the gearboxes of individual robot axes during collisions or other events. Cobot manufacturers can use this added value for precise collision monitoring without additional torque sensors. 

Modular angle encoder systems from AMO and RSF: secondary encoders for wide-diameter robot motors 

Using a second high-accuracy angle encoder on a robot axis helps robot manufacturers to significantly improve absolute positioning accuracy. Mounted downstream from the gearbox, secondary encoders track the real-world position of every robot axis, thus enabling a host of new applications. 

Modular solutions for this task are the WMRA from AMO and the new MCR 16 angle encoder from RSF. Thanks to their modular design with a scale drum or measuring ring and a separate scanning unit, they include solutions for large shaft diameters or tight installation spaces. Featuring a versatile mechanical design, the secondary encoders from AMO also achieve high robustness through inductive scanning technology. Meanwhile, the MCR 16 from RSF offers optical scanning with improved signal quality for absolute position measurement on large axes.
