XENSIV™ AS5311 Hall magnetic linear sensor with a 12-bit incremental digital interface and ABI/PWM outputs The AS5311 is an incremental position sensor for linear and rotary off-axis applications based on contactless magnetic sensor technology. To measure position and motion a multi-pole magnet strip or ring has to be used. There are 4096 pulses (12-bit) per 2.0 mm pole pair length on the standardized quadrature output interface with an index pulse (=ABI-interface) with a maximum speed of 650mm/s.
