16-bit Hall-effect magnetic encoder for
sensing position in harsh conditions
Avago Technologies has announced the 16-bit resolution
Hall-effect magnetic encoder for sensing positioning information
in a harsh operational environment of industrial applications
such as contactless rotary position sensing, robotics, motor
feedback and valve control, as well as for medical applications.
The AEAT-6600-T16 magnetic encoder offers precise angle
measurement over a full rotation of 360 degrees and the
use of magnetic technology for motion control and sensing
activities enables non-contact operation free from mechanical
wear and tear. The encoder is a system-on-chip combining
integrated Hall elements, analog front end and digital signal
processing in a single device,and also featuring with built-in
programmability to allow customized encoder settings, providing
significant savings for customers' encoder inventory, as
per Avago.
"The Avago AEAT-6600-T16 encoder delivers leading
precision for motion control systems with highly durable
magnetic technology in a small form factor, building on
our industry leadership in high-resolution magnetic reflective
encoders," said Hassan Hussain, general manager of
the Motion Control Products Division at Avago. "The
device expands the reach of our complete optical and magnetic
encoder portfolio, addressing applications operating in
severe industrial conditions."
Avago says the AEAT-6600-T16 device offers simple one-step
alignment with no calibration required, avoiding handling-related
issues during setup and reducing assembly time and costs
and delivers accurate performance over a large axial gap
and radial displacement, reducing concerns related to assembly
tolerance errors during the manufacturing process and also
offers serial output, reducing the number of wires required.
The encoder is available in a small 16-pin TSSOP package
and features low supply voltage, suitable for portable,
battery-operated applications.
Other features of AEAT-6600-T16 encoder include:
Simultaneous incremental output of up to 1024 cycles per
revolution (CPR)
Wide operating temperature range from -40° to 125°
C
3-wire or 2-wire Serial Synchronous Interface (SSI) interface
mode for absolute output
Pulse Width Modulation (PWM) and incremental output modes
Internal voltage regulator for 5V or 3.3V operation
Power-down mode to reduce current consumption
RoHS compliant
U.S. Pricing and Availability
The Avago AEAT-6600-T16 magnetic encoder is priced at $6.50
each in 970 piece quantities (10 tubes). Samples and production
quantities are available now
