ALT521 Transfer Function  
 
World’s Most Sensitive Ultraminiature Rotation Sensor
The new ALT521-10E sensor has two independent magnetic sensing axes, each with a high-sensitivity 140 mV/V/mT output. The sensor can detect rotating fields as small as 0.1 µT.
 
 
Omnidirectional Sensing  
 
 
Omnidirectional Sensors
Magnetoresistive sensors are sensitive in-plane, while Hall effect sensors are sensitive perpendicular to the IC plane. NVE’s amazing omnidirectional sensors combine the best of both worlds—sensitive in both directions and anything between.
 
 
 
ALT021-10E-EVB02   
  
Amplified Ultrasensitive TMR Sensor Evaluation Board
The new evaluation board includes an ultrasensitive ALT021-10E TMR magnetic sensor and a 5x amplifier. The 13 x 8 mm PCB has a remarkable sensitivity of 2.5 V/V/Mt.
 
 
MSOP Isolators  
 
The World’s Smallest 2500-Volt Isolators
V-1 Series MSOP8 isolators are just three millimeters square—less than an eighth of an inch—but still feature 2500 Vrms VDE 0884-17 and UL 1577 isolation ratings.
 
 
Breakout Boards  
New Sensor Breakout Boards
Now available for most NVE sensors, the 0.8 x 0.4 inch (21 x 10 mm) boards have pre-soldered sensors, bypass capacitors if required, 0.1" headers, and 1 mm-pitch edge connectors.
 
H-bridge Arduino Shield  
 
Angle/Rotation Sensor Arduino Shield
The Shield is compatible with all 12 of NVE’s TMR angle and rotational sensor breakout boards.

A magnet fixture allows the magnet to be positioned on-axis or in one of four off-axis positions. Sixty RGB LEDs indicate the angle, and colors indicate direction of rotation.
 
 
Current Sensor Eval Boards  
Noncontact Current Sensor Evaluation Boards
These current-sensing boards have pre-soldered sensors, screw terminals, 0.1" headers, and 1 mm-pitch edge connectors. Three current ranges are available: 0 to 1 amp, 0 to 7 amps, and 0 to 50 amps.
 
7 kV Isolation  
 
7 kV Isolators
IL700VE-Series isolators were upgraded to an incredible 7 kV reinforced isolation, the best in class by far.
 
 
DFN4  
 
The World’s Smallest High-Sensitivity Magnetic Sensor 
A TMR magnetometer sensor with best-in-class sensitivity of 200 mV/V/MT and up to 0.1 µT detectivity was introduced in a 1.1 x 1.1 mm DFN4 package. The new part can be connected directly to ADC or microcontroller analog inputs.
 
 
WLCSP  
 
WLCSP Magnetic Switches
Several 1.5-volt magnetic switches were introduced in ultraminiature Wafer-Level Chip-Scale packages (WLCSPs). The new parts are available with a variety magnetic operate points, with or without duty cycling.
