AS5304 Linear Position Sensor

160-Step Linear Incremental Position Sensor with ABI Output

The AS5304 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 160 pulses per 4.0 mm pole pair length on the standardized quadrature output interface with an index pulse (=ABI-interface) with a maximum speed of 20m/sec.
