A 0.8 x 0.4 inch (21 x 10 mm) breakout board with the ADT001-10E quadrant rotation sensor.
The board has a pre-soldered sensor and footprints for a standard 0.1" (2.54 mm) header and a common, 1 mm pitch card-edge connector.
The board can be powered by a 0 to 5.5 V supply and provides sine and cosine digital quadrature outputs.
A 0.8 x 0.4 inch (21 x 10 mm) breakout board with the ADT002-10E low-hysteresis quadrant rotation sensor.
The board has a pre-soldered sensor and footprints for a standard 0.1" (2.54 mm) header and a common, 1 mm pitch card-edge connector.
The board can be powered by a 0 to 5.5 V supply and provides sine and cosine digital quadrature outputs.
ADT002-10E Rotation Sensors provide two binary digital outputs to accurately indicate the absolute rotational quadrant of a rotating magnet. The two outputs are 90 degrees out of phase to also provide directional information.
The ADT002 is lower hysteresis than the ADT005 to provide accurate, absolute rotational quadrant information.
The sensors use NVE’s unique Tunneling Magnetoresistance (TMR) technology to minimize power consumption and size.
The sensors are typically used with
radially-magnetized disk magnets or split pole magnet.
An Evaluation Kit is available with an angle sensor, magnet, circuit board with indicator LEDs, and a plastic magnet locating fixture.
Note: Please purchase in increments of 100 when purchasing quantities of 100 or more.
A 0.8 x 0.4 inch (21 x 10 mm) breakout board with the ADT005-10E ultralow power quadrant rotation sensor.
The board has a pre-soldered sensor and footprints for a standard 0.1" (2.54 mm) header and a common, 1 mm pitch card-edge connector.
The board can be powered by a 0 to 5.5 V supply and provides sine and cosine digital quadrature outputs.
ADT005-10E Rotation Sensors provide two binary digital outputs to accurately indicate the absolute rotational quadrant of a rotating magnet. The two outputs are 90 degrees out of phase to also provide directional information.
The ADT005 is higher hysteresis than the ADT002 for high noise immunity in applications such as speed sensing and counting rotations or where motion is in only one direction.
To minimize power, the ADT005 does not include
the high-field detection circuitry included in the ADT001 version, and is slightly less accurate due to lower-power circuitry.
The sensors use NVE’s unique Tunneling Magnetoresistance (TMR) technology to minimize power consumption and size.
The sensors are typically used with
radially-magnetized disk magnets or split pole magnet.

NVE's ADV001-00E is a GMR Digital Switch using a bipolar output GMR material.
This material allows the sensor to maintain an operate point with the application
of a negative (South) magnetic field, and a release point with the application
of a positive (North) magnetic field. The part is ideal for use with magnetic
encoders that have alternating North/South poles, or in any other application
where one polarity of field is required to turn the part on, and the opposite
polarity is required to turn it off.
