Produkt-Neuheit

NVE's ultrasensitive ALT021-10E Tunneling Magnetoresistance (TMR) analog magnetometer can precisely measure fields from less than a microtesla to 250 microtesla. The differential bridge outputs are bipolar, meaning positive for a positive field and negative for an opposite field polarity. Key specifications include:

• High sensitivity (500 mV/V/mT typical)
• Large signal (200 mV/V typical full-scale)
• Flexible 0 to 10 V supply (no minimum)
• 20 kiloohm device resistance for low power
• ±0.25 mT linear range
• High linearity (2% of full-scale)
• Ultra-low output temperature coefficient (±0.1%/°C)
• Up to 300 kHz bandwidth
• –40 to 125 °C operating range
• 2.5 x 2.5 mm DFN package

ALT021-10E TMR sensors are suitable for a variety of applications requiring wide sensing range and robust airgap and alignment tolerance:

• Proximity sensing
• Motion, speed, and position control
• Ferromagnetic material detection
• Flow sensing
• Geomagnetic navigation
• Noncontact current sensing
• Wearables
• Mechatronics and robotics
