NEW! 1.5-Volt Nanopower TMR
Magnetic Switches
 
Revolutionary new AHT-Series Tunneling Magnetoresistance (TMR) magnetic switches are low-voltage, nanopower, high speed, and ultraminiature.

Single-Cell Operation
AHT-Series sensors operate as low as 0.9 volts, so they can be powered by single-cell alkaline batteries.

Ultralow Power
TMR technology provides ultralow power. Typical AHT-Series quiescent supply current is just 1 µA, even with no duty cycling. That’s less than the self-discharge rate of typical button cells, making the new sensors ideal for battery applications such as utility meters or portable instruments.

Speed and Wide Bandwidth
Continuous operation without duty cycling means the sensors are fast, and can switch at more than 1.5 kHz.

Sensitive
Magnetic operate points are as low as 1.5 mT (15 Oe).

Configured as Switches
Outputs are configured as magnetic “switches,” turning on when a magnetic field is applied and off when the field is removed. The field can be either polarity, and the magnetic operate point is extremely stable over supply voltage and temperature.

AHT-Series Sensors fit on the head of a pin

NEW! Smart Sensor Breakout Boards
 
NVE expanded its Smart Sensor support ecosystem with breakout boards for all four NVE Smart Sensors. The boards include a Smart Sensor, six-pin header, and a bypass capacitor, making it easy to evaluate the sensors and build prototypes:The AG958-07E Breakout Board also has a connector to for use with the AG955-07E Self-Contained SM124 Programmer or with customers’ own boards.

In addition to the breakout boards, NVE offers Smart Sensor evaluation kits that include evaluation boards with microprocessor USB interfaces to Windows-based computers.
 
ISO9001 and IATF 16949 Renewed
IATF 16949
 
NVE’s ISO9001 certificate and IATF16949 Letter of Conformance have been renewed.

The IATF Letter certifies that NVE has established and applies a Quality Management System for components for the automotive industry.

NVE makes a number of products for automotive applications, including CAN and CAN FD isolated transceivers, as well as a wide range of magnetic sensors.
