New GMR magnetometer breakout boards

We’re introducing a new family of GMR magnetometer breakout boards. There are dozens of them, all in stock for immediate delivery.
We take a closer look at our most sensitive GMR sensor, the AAH002, which revolutionized magnetic sensing.
We get a large signal, and can detect a small magnet a long distance away independent of polarity.
Although many customers are now using our TMR sensors, our venerable AA-Series Analog GMR Sensors are still popular. Advantages of these sensors include:
• Wide supply ranges including direct connections to 12 and 24-volt systems;
• Low output impedance for easy interface;
• They’re omnipolar, so you don’t have to worry about magnetic polarity;
• And they’re available in easy to handle packages.
We have an extraordinary range of sensors, so there’s sure to be one for your application.
Email sensor-apps@fornve.com for more information.
Here's a link to more information on the new boards:

Hot dog cooker interlock sensors

Переглядів 4221 день тому

In this last video in this series, we show two types of magnetic interlocks to detect if a hot dog cooker cover is open. This allows shutting off the power for safety, and is a common application for our sensors. The first circuit uses the magnetometer section of the smart sensor to detect the field from a magnet on the cover. The sensor also has a temperature section we used to measure the hot...

Hot dog cooker temperature sensor

Переглядів 3628 днів тому

We've added a temperature sensor to our hot dog cooker to ensure the hot dog is cooked to a safe temperature. We used an isolator between the sensor and the Arduino because the sensor is in contact with the hot dog and therefore in contact with high voltage. The isolator also functions as a level shifter between the 3.3-volt sensor and the five-volt Arduino. Rectified AC powers the hot dog via ...

In this video, we unbox an evaluation board and demonstrate our new ALT026-10E Tunneling Magnetoresistance (TMR) analog magnetometer with an Arduino. NVE has expanded its industry-leading line of ALT-Series TMR magnetometers with the ALT026-10E. The new version has a 20 mT linear range, which is the widest in the Series. The part family's best-in-class specifications include: • High sensitivity...

Hot dog cooker with current sensing

Переглядів 38Місяць тому

This hot dog electrocutor uses a current sensor to cook based on total applied energy. The sensor also provides overcurrent detection for improved safety. Rectified AC powers the hot dog as we described in previous videos. We cook the hot dog to a perfect 7 kilojoules, just like it says on the package. Here are links to the key parts in this demo: Current Sensor Evaluation Board: www.nve.com/we...

Improved hot dog cooker power control

Переглядів 147Місяць тому

Improvements make this hot dog cooker version a bit less unsafe than previous versions. We use full-wave rectified AC to avoid a dangerous high-voltage filter capacitor. The power control uses an isolator, DC-to-DC convertor, and silicon carbide FET. The unique DC-to-DC convertor provides an isolated five-volt supply to power the isolator plus an isolated nine-volt gate supply. We use a variabl...

New Isolator Evaluation Boards

Переглядів 213Місяць тому

We recently launched dozens of new isolator evaluation boards to let you easily try out NVE's unique spintronic isolators. These 2 x 3.5-inch (50 x 90 mm) boards contain your choice of isolator, bypass capacitors as recommended, screw terminals, and provisions for header pins. For isolators with integrated DC-to-DC convertors, there are LEDs to show the DC-to-DC convertor is working. The boards...

Isolated Hot-Dog Cooker

Переглядів 2202 місяці тому

We've cooked hot dogs using line voltage on other demos to show the danger of unisolated high voltage. In this demo, we’ll show a controlled, isolated hot-dog electrocutor. The circuitry is important for applications such as battery charging and motor control. A silicon carbide FET modulates the voltage to the load. An isolator protects the controller. A DC-to-DC convertor provides an isolated ...

Isolators transmit data or power without an electrical connection. A key benefit is electrical safety. In this demonstration, a creepy doll represents a person, and a resistor represents human tissue. If we touch something, like an appliance that's at a different potential and not isolated, a dangerous current could go through us. We show that one of our isolators can withstand 2500 volts for o...

In this demonstration, a creepy doll represents a person and a hot dog represents human tissue. If we touch something like an appliance at line voltage, a dangerous current could go through us. [Disclaimer: Don't try this yourself. Un-isolated line voltage could cook you like a hot dog.] If we add an isolator, even with a dangerous voltage on the input, the output is perfectly safe. Nothing hap...

The IL610A Is 1000x Faster than an Optocoupler

Переглядів 1913 місяці тому

We demonstrate the huge speed advantage of our IsoLoop isolators compared to optocouplers. We show that the state-of-the-art IL610A spintronic isolator is nearly a thousand times faster than the venerable 4N28 optocoupler. The IL610A has a current-mode input and an open-drain output, so it works just like an open-collector optocoupler, only better. They're also available with CMOS outputs, and ...

We demonstrate a 2xMOPP medical interface using NVE’s ground-breaking data couplers with integrated DC-to-DC convertors. We use a creepy doll with an ECG simulator as a “patient.” A high-pot tester is set for four kilovolts, which is required for 2xMOPP. The tester is set for a 0.3 milliamp fail-current threshold, which is the toughest limit under UL 60601. A beeping ECG detector shows data is ...
