We will soon introduce the AksIM-4™ absolute encoder with HIPERFACE DSL® (HDSL) protocol. This upcoming product will combine the proven capabilities of the AksIM-4™ series with seamless one-cable connectivity for servo motor applications – setting a new benchmark for compact, high-resolution motor feedback systems. AksIM-4™ will be the first open PCB hollow shaft encoder supporting HDSL communication protocol.

Already established as the absolute no. 1 position encoder in robotics, the AksIM-4™ will be further optimized for automation and embedded motion control platforms through the integration of the HDSL protocol – a fast, digital communication protocol based on RS-485.

The AksIM-4™ HDSL will be developed for space-constrained applications in industrial automation, and servo systems. Its flat PCB readhead combined with axially magnetised rings will enable precise, non-contact absolute position feedback, while minimizing system integration complexity. In addition, the encoder will support advanced features such as real-time temperature and speed monitoring, diagnostics and self-calibration through a robust resource communication structure.

“The AksIM-4™ will be a perfect addition to our portfolio of HIPERFACE DSL supporting products and supporting a multi-sourcing strategy of OEMs. Its open PCB and hollow-shaft design will offer the kind of flexible, high-performance encoder our customers are looking for in integrated and space-sensitive motor solutions.”

The integration of the HDSL protocol will enable power and communication to be transmitted over a single shielded twisted pair – reducing cable volume, simplifying installation, and allowing real-time data exchange for predictive maintenance and enhanced machine diagnostics. The protocol will support plug-and-play functionality and data handling, helping machine builders streamline commissioning and improve system reliability.
