AS5035, an 8-bit incremental magnetic rotary encoder for cost-sensitive industrial and automotive applications, is suited for use in human-machine interface applications, such as front panel switches, or as an alternative to optical encoder-based applications where dust or other particles could diminish reliability and accuracy.
 
Provides incremental quadrature A/B output signals and an index output signal. The index signal represents a mechanical reference point, called the zero position, which can be programmed by the user at the system assembly stage. Operation safety is ensured by continuous monitoring of the magnet presence and the optimal magnet position in the system. 
 
Features 64 pulses per revolution on each of the two quadrature output channels, for resolution of 2.8°/step over a full turn of 360°. Failure detection monitors the magnet's placement during the operation. In case of a missing or loose magnet, the device instantly provides a warning signal.
 
Operates at rotational speeds up to 10,000 revolutions/min.,  at either 3.3 or 5 V, without missing any incremental pulses. The zero position can be programmed by the user. Operating temperature ranges from -40 to +125°C. Available in a lead-free SSOP 16 (5.3mm x 6.2mm) package.
