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
