DATA SHEET MBD07_05 Issue 05, 6th May 2024 AksIM-2 Off-Axis Rotary Absolute Redundant Magnetic Encoder HIGH ACCURACY HIGH SPEED The AksIM-2 redundant encoder is an advanced series of non-contact, high performance off-axis absolute encoders suitable for applications requiring a higher level of safety. The AksIM-2 redundant encoder system consists of two identical, completely independent and electrically isolated encoder modules combined on one PCB and a separate axially magnetized ring. HIGH SAFETY The encoder is a redundant solution and part of the AksIM-2 absolute encoder range. For technical specifications not included in this document, refer to the latest version of MBD01 data sheet, available for download from the AksIM-2 website. Proven AksIM-2 true absolute encoder technology Redundant version for higher safety applications Simple installation and easy connection COLLABORATIVE ROBOTS BiSS communication interface Excellent price-performance ratio ROBOTIC JOINTS

General information With its compact and innovative design, the AksIM-2 redundant encoder system allows easier installation and is available in two dimensions. Two encoder modules on one PCB give much more freedom in designing advanced motion control systems to monitor the encoder position via two independent channels. The redundant AksIM-2 encoder is available with the advanced BiSS communication protocol with differential signaling (RS422). With resolutions up to 20 bits and accuracy better than ±0.05°, high performance is assured when the encoder is installed within the required tolerance....

Storage and handling Storage temperature Operating temperature ¢40 °C to +85 °C –40 °C to +105 °C (Extended temperature range) –40 °C to +85 °C –40 °C to +105 °C (Extended temperature range) This encoder system is a high performance metrology product and should be handled with the same care as any other precision instrument. The use of heavy duty industrial tools or exposure to strong magnets such as a magnetic base is unacceptable and carries the risk of irreparable damage to the product. The magnetic ring should not be exposed to magnetic field densities higher than 50 mT on its surface, as...
