CUI Devices has announced an incremental encoder for motors with shafts between 1 and 6.35mm in diameter.

CUI AMT12 incremental encoder
“The AMT12 series brings the same durability, accuracy and immunity to environmental particulates as current AMT encoder models in a more compact 22.2 x 22.2 x 12.8mm package,” according to the company.

Outputs are single-ended cmos quadrature A and B signals that can sink or source 2mA. Rise and fall times are 30ns.

The encoders are programmable to select one of 16 resolutions across 96 to 4,096 pulse/rev, and the zero position, using graphical user interface software called ‘AMT Viewpoint’ which works with Windows 10 and higher. Parts can be ordered pre-programmed.

Maximum rotational speed is 4,000rpm at resolutions of 384, 768, 800, 1,000, 1,600, 2,000, 2,048 or 4,096 pulse/rev, and 8,000rpm at 96, 192, 200, 250, 400, 500, 512 or 1,024 pulses/rev.

Consumption is 16mA from 5V, and operation is over -40 to +125°C.

The units come in two styles, one with connector pins parallel to the operating shaft (‘axial orientation’ AMT123S-V pictured) and the other with connector pins outwards at 90° (‘radial orientation’ AMT122S-V).

Each is available with a kit of colour-coded adapters for different shaft sizes, that also includes moulded tools to aid installation.

Robotics and industrial automation applications are foreseen.
