Product Description

MagnTek’s rotary position sensor MT6826Si s a n I C b a s e d o n a d v a ncedAMRtechnology. A rotating magnetic fieldinthex-y sensor plane delivers twosinusoidaloutput signals which indicatingtheangle(α) between the sensor andthemagneticfield direction.

The incremental ABZ output modeisavailable in this sensor series, makingthechip suitable to replace variousopticalencoders. The maximumresolutionis4,096pulses or 16,384 steps per revolution. Themaximum resolution of incremental UVWis16 Pole-Pairs per.

A 4-Wire SPI interface allowsahostmicrocontroller to read out the15-bitabsolute angle position data fromMT6826S.The absolute angle position is alsoprovidedas a 12-bit PWMoutput.

The core performance improvementofMT6826S is the self-calibrationmodewhichcan compensate for the non-linearitycaused by the unsatisfactory magnetandthe structure installation.
