PART NUMBER: AMT203
THE AMT203 is a high performance
absolute encoder based on capacitive
sensing technology. The AMT203
utilizes a custom ASIC to create
absolute position over a single
turn. This encoder is12 bit and
communicates via an SPI serial bus
for working as a slave to an external
microprocessor. Incremental A,B
signals with a single index pulse
per 360 deg are provided for higher
speed operation.
