Austriamicrosystems' AS5035 is an eight-bit incremental magnetic rotary encoder for cost-sensitive industrial and automotive applications. The device is well suited for use in human-machine interface (HMI) applications, such as front panel switches, or as an alternative to optical encoder-based applications where dust or other particles could severely diminish the reliability and accuracy of the system operation.

The AS5035 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.

The AS5035 is an encoder solution for cost-sensitive applications that have been using optical encoder solutions. Another key product feature is the ability to program the zero position at the system assembly stage.

The AS5035 provides 64 pulses per revolution on each of the two quadrature output channels, which equals a resolution of 1.4 ° per edge over a full turn of 360 °. Operation safety is ensured by a failure detection feature, which monitors the magnet's placement during the operation. In case of a missing or loose magnet, the device instantly provides a warning signal. The IC operates at rotational speeds up to 10,000 revolutions per minute, without missing any incremental pulses. The zero position can be programmed by the user. The AS5035 operates at either 3.3 V or 5 V. The operating temperature ranges from -40 °C to +125 °C. The AS5035 is available in a lead-free SSOP 16 (5.3 mm × 6.2 mm) package. The AS5035 is sampling now.
