AMT203 encoder

CUI Inc. has added a new absolute encoder to its high-resolution, low-cost AMT modular encoder line.

The AMT203 outputs 12bit of absolute position information in a very small (1.35"x1.13"x 0.45") modular package. The AMT203 generates absolute position information using CUI's patented, capacitive code generation system coupled with a proprietary ASIC, creating a reliable, economical and durable control and positioning solution.

The encoder consumes a maximum 10mA at 5Vdc, making it well-suited for applications where power consumption is a concern. Available options include nine mounting patterns and ten bore sizes, creating a flexible platform that is able to mate with many industry standard motors.

The AMT203's SPI affords higher throughput and simpler hardware interfacing than I?C or SMBus. Using TCL code, the on-board PIC 16F690 microcontroller operates at up to 2MHz providing for high speed applications.

Zero position may be set by SPI command or ground trigger, removing the need for time consuming mechanical alignment in the mounting process.

Additionally, the AMT203 provides a non-magnetic index pulse and may be configured to output incremental position data after zero position is established to approach throughput of up to 10MHz.

Pricing is $63 per unit through distributor Digi-Key.
