AMT203_10 Datasheet, PDF (1/6 Pages) CUI INC – 12 BIT AB SOLUTE ENCODER

PART NUMBER: AMT203
date 10/2010
page 1 of 6
DESCRIPTION: 12 BIT ABSOLUTE ENCODER
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
and Index signals are provided for
higher speed operation. Incremental
A,B signals with a single index pulse
per 360 deg are provided for higher
speed operation.
FEATURES
- 12 bit (4096 positions)
- SPI communication
- Small Size 37mm
- Incremental Line count up to 1024
- Single pulse index
- Capacitive ASIC technology
- Modular locking hub design
for ease of installation
- SPI adjustable settings
- ‘One Touch’ zero position
