NVE offers sensor evaluation kits at nominal cost so customers can evaluate these remarkable devices. A number of kits are available:
This kit features several types of NVE’s AA and AB series parts, a selection of permanent magnets for activation or bias purposes, and circuit boards to mount the parts for testing.
This kit features a specially designed circuit board with traces running under the sensor elements. The customer can try different current levels to see the output from the sensor.
Several GMR Switches with different magnetic operate points and different output options such as current sink and current source. Magnets and circuit boards for mounting the parts are also included. The AG910-07 kit also includes a zero insertion force (ZIF) socket for easy testing of the MSOP packages.
The kit includes a demo board our most popular sensor types: digital, analog, omnipolar, and bipolar. Each sensor drives an indicator LED. A bar magnet is included so you can see for yourself how these remarkable sensors work. The evaluation boards are 3.75 x 5 inches (95 x 127 mm), and are powered by two coin cells (included).
The kit includes a demo board with three ultraminiature, ultralow-power ADL-Series magnetic sensors. Each sensor drives an indicator LED, and a meter shows the sensor power in microamps or nanoamps. A bar magnet is included so you can see for yourself how these remarkable sensors work. The evaluation boards are 3.75 x 5 inches (95 x 127 mm), and are powered by a coin cell (included).
Evaluate gear tooth sensors for measuring rotational speed with a variety of analog and digital GT Sensors, plus the DD001-12 stand-alone signal processing IC. A variety of PCB configurations are provided so the parts can be tested in different housing and barrel sizes, including the M8 housing. Biasing magnets are also included.
NVE’s newest evaluation kit is a self-contained demonstrator for NVE’s unique AKL digital gear tooth sensor. The battery-powered demonstrator (battery included) is based on an AKL002 sensor. The demonstrator also includes a circuit board with an LED and driver, a biasing magnet, and a gear that can be turned by hand. No assembly required. Dimensions 3″ x 3″ x 1.5″.
AG93x-07—Angle Sensor Evaluation Kits
Includes an evaluation circuit board with a reference design AAT-Series Sensor and a unity-gain buffer amplifier. A split-pole magnet and a plastic magnet locating fixture are included in the kit. An angular reticle on the circuit board aids in characterizing output versus angle. Three versions are available for three different AAT-Series sensors:
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.
These kits include demo boards with the ultraminiature, ultralow-power ADL021 magnetic switch. An LED shows the sensor output. A bar magnet is included so you can see for yourself how these remarkable sensors work. Sensor quiescent current is only 100 nA typical; the sensor operate point is 20 Oe; and the sensors are 1.1 mm x 1.1 mm. These miniature evaluation boards are just 0.25 x 1.57 inches (6 x 40 mm). There are two versions: the AG040C is externally-powered, and the AG040B is powered by a coin cell (included), and the sensor quiescent power consumption is so low, the battery will last indefinitely.
