NVE Introduces Smart I²C TMR Angle Sensor

March 26, 2020 Tiera Oliver

NVE Corporation expanded its line of angle sensors with the new ASR012-10E Smart I²C TMR Angle Sensor.

The ASR012 is based on the same TMR sensor element and digital processing core as the ASR002, but with an Inter-Integrated Circuit (I²C) rather than a Serial Peripheral Interface (SPI). The new part also provides a pulse-width modulated (PWM) output.

Both the ASR012 and ASR002 have factory-calibrated Tunneling Magnetoresistance (TMR) sensor elements and digital signal processing.

Key ASR022 and ASR002 features include:

  • Factory calibrated

  • 0.1 degree resolution

  • 0.2 degree repeatability

  • Robust 6 to 20 millitesla magnetic field operating range

  • Fast 12.5 kilosamples per second sample rate

  • Flexible 2.2 to 3.6 volt supply range

  • Low 4 milliamp typical supply current

  • Wide -40 to +125 degrees Celsius operating range

  • Ultraminiature 2.5 by 2.5 by 0.8 millimeter package

Sensors and evaluation kits are available now for immediate delivery. The ASR012-10E sensor is priced at $2.22 each in 1000-piece quantities.

The ASR012 Evaluation Kit (part number AG963-07E) includes a magnet assembly, magnet fixturing, and PC-based user interface software. Kits are priced at $195 each.
