SM124, SM225, SM324
GMR and TMR current sensors
SMxxx smart magnetometers offer precise magnetic field measurements. The sensors combine Giant Magneto Resistance (GMR) (SM124) or Tunnel Magneto Resistance (TMR) (SM225, SM324) sensing elements with easy-to-use digital signal processing.
Unlike Hall-effect sensors, GMR is sensitive in the right plane for optimal current sensing and simple mechanical interfaces. GMR and TMR also offer greater sensitivity, higher precision, higher speed and much lower noise than Hall-effect sensors. A digital output provides precise, programmable thresholds. An I²C (SM124, SM324) or SPI (SM225) interface provides magnetic field data as well as a calibration interface.
- Over 5 cm range
- Sensitivity is at component level - unlike Hall sensors, which must be mounted perpendicular to the current flow
- Internal temperature compensation
- I²C or SPI interface
- Ultra-miniature 2.5 x 2.5 x 0.8 mm TDFN6 housing
- -40...125°C Operating temperature range
Under the brand name IsoLoop, NVE has developed several series of couplers and transceivers for high-speed data transmission on a magnetic basis.
NVE Corporation is a leader in the practical commercialization of spintronics, a nanotechnology that relies on electron spin rather than electron charge to acquire, store and transmit information.
The company manufactures high-performance spintronic products including sensors and couplers that are used to acquire and transmit data. Products offer smaller size, more precision, higher speed, and are more rugged than coventional devices. NVE parts are popular in industrial, scientific, and medical applications. Sensors acquire information, couplers transmit information, and memories store information. Thus our technology can provide the eyes, nerves, and brains of electronic systems. NVE's award-winning products are sold through a worldwide distribution network.
NVE was founded by Dr. James M. Daughton, a former Honeywell executive, in 1989. The company is located in Eden Prairie, Minnesota, a suburb of Minneapolis.
