Avago Technologies has launched its high-resolution Hall-effect magnetic encoder, the AEAT-6600-T16. According to Avago, the encoder offers advanced positioning information with the robust performance required for the 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 Avago AEAT-6600-T16 magnetic encoder offers up to 16bit resolution for precise angle measurement over a full rotation of 360. 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. Along with this high level of integration, the encoder features built-in programmability to allow customised encoder settings, providing significant savings for customers' encoder inventory.

Additional features of the AEAT-6600-T16 encoder include: 1) simultaneous incremental output of up to 1024 cycles per revolution (CPR); 2) wide operating temperature range from -40C125C; 3) 3-wire or 2-wire serial synchronous interface (SSI) mode for absolute output; 4) pulse width modulation (PWM) and incremental output modes; 5) internal voltage regulator for 5V or 3.3V operation; 6) power-down mode to reduce current consumption; 7) and it is RoHS compliant.

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. The encoder delivers accurate performance over a large axial gap and radial displacement, reducing concerns related to assembly tolerance errors during the manufacturing process. The device 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, targeted for portable, battery-operated applications.

Samples and production quantities of the Avago AEAT-6600-T16 magnetic encoder are available now. Avago is also offering the HEDS-8937 programming kit designed specifically for the AEAT-6600-T16 encoder.
