The AS5311 from Austriamicrosystems AG, Unterpremstaetten, Austria, is a Hall-effect sensor-based linear magnetic encoder capable of submicron resolution. For linear motion sensing, a multipole magnetic strip is used and for rotary motion sensing the magnetic strip is replaced by a multipole magnetic ring. An incremental output with 10-bit resolution per pole pair and a traveling speed up to 650 mm/s is available. 16-bit resolution is possible using a multipole magnetic ring with a 41.7 mm dia. Used with a 2 mm pole-pair magnetic strip the device provides a 1.95 µm resolution signal (incremental) and a 488 nm resolution signal (serial output). The encoder chip also constantly monitors the placement of the magnet above the device, allowing early detection of mechanical systems failures.
