A self-contained demonstrator for NVE’s unique AKL digital gear tooth sensor.The battery-powered demonstrator (battery included) is based on an AKL001 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".
The kit includes a circuit board with an AAT009-10E 6 megohm Angle Sensor and a unity-gain buffer amplifier. The circuit board can be powered with a 1.7 V to 5.5 V power supply. An angular reticle on the circuit board aids in characterizing output versus angle.
The kit also includes a split-pole magnet and a plastic magnet locating fixture.
The AAT009-10E Angle Sensor has ultra-ultra low power consumption and is ideal for long-term battery-powered operation or operation from harvested power.
The AG954-07E provides a socket for easy programming and prototyping of TDFN6 devices without soldering and unsoldering.
The custom socket is compatible with NVE's 2.5 mm x 2.5 mm TDFN6 package parts (-10E suffixes).
The board is 1.5" x 2" (38 mm x 50 mm), and uses brass hardware to minimize magnetic interference with the socketed sensor.
A 0.1"-spaced header provides for connections to the sensors, and a row of 0.1"-spaced through-holes allows for auxiliary parts such as a decoupling capacitor or an LED.
This self-contained module allows zeroing and programming the digital output threshold and hysteresis or SM124-10E or SM125-10E Smart Magnetometer without need of a computer or a customer microcontroller.
The 2.5" x 2.5" (64 mm x 64 mm) board has an I²C master microcontroller connected to the SM124.
A pushbutton for zeros the sensor, and miniature rotary thumbwheel switches provide three digits of resolution for the threshold and two for hysteresis. A custom TDFN-6 socket accommodates the 2.5 mm x 2.5 mm SM12x-10E. The module is powered by a small wall-mounted power supply (included).
Jumpers allow the sensor to be disconnected from the rest of the board so the board can be used as an interface to the customer’s electronics.
This module includes:
A 2.5 x 2.5 mm TDFN6 socket for a SM12x-10E Smart Magnetometer
A preprogrammed, onboard microcontroller
Two sets of thumbwheel switches for digital threshold and hysteresis
Two LEDs indicating the sensor’s output and successful programming
