The AksIM™ is a non-contact high performance off-axis absolute rotary encoder designed for applications with limited installation space. The compact, low profile readhead detects and evaluates the magnetic field of a thin, axially magnetized ring.
The 49 mm ring offers 524,288 positions per revolution at a resolution of 19 bits while the larger, 80 mm ring, provides 1,048,576 positions at a resolution of 20 bits. The accuracy of the AksIM™ magnetic encoder system is better than ±0.1° and the maximum permissible speed is over 10,000 revolutions per minute.
The low overall system height together with its true absolute functionality and high speed operation make the new single-track absolute encoder suitable for a wide range of applications including video-surveillance systems measuring the angle of camera rotation, robotic arm joints and motors for detecting position.
