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.
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.

A smart business card that demonstrates the ADT925-14E 1.1 x 1.1 mm DFN4 TMR Switch sensor.
The board can be plugged into a USB TYPE-A connector, such as those on a computer, for power. An LED on the card shows when the sensor is activated. A small neodymium magnet is included to activate the sensor.
You can carry it with you so you're always prepared to demonstrate the high sensitivity, low power, and small size of TMR sensors.

The AG040T Demonstration Board has an ADT923 TMR magnetic switch powered by a three-volt lithium coin cell (included). An LED to show the sensor output. The sensor’s low quiescent power allows the battery to last at least several years with occasional LED use.
A miniature bar magnet is included so you can see for yourself how these remarkable sensors work.
The sensors are 1.1 mm x 1.1 mm x 0.35 mm, and these miniature evaluation boards are just 0.25 x 1.57 inches (6 x 40 mm).
The kit includes a circuit board with an ADT002 low hysteresis, ultralow-power rotation sensor, a split-pole magnet that can be turned, and simple circuitry to drive LEDs from the sensor outputs. Two LEDs follow the sensor outputs; four others indicate the rotational quadrant.
A 3-volt coin cell (included) powers the board.
