The
World’s Most Sensitive
Magnetic Switch |
|
|
The newest member of
NVE’s industry-leading family of magnetic switches, the AFL006, is also the
most sensitive, with a remarkable 4 Oersted typical operate point.
Key AFL006 features include:
• 4 Oe operate point for ultrahigh sensitivity
• 0.9 V – 2 V operating voltage for single-cell battery
operation
• Power less than 100 microwatts
• 2.5 mm x 2.5 mm x 0.8 mm
TDFN6 for miniaturization
Applications include portable instruments, utility meters, and noncontact overcurrent
protection.
Like most of our GMR switches, the AFL006 is omnipolar, meaning the applied field
can be of either polarity, and the operate point is extremely stable over supply
voltage and temperature. Magnetic hysteresis is low for precise operation.
There are now three off-the-shelf versions of NVE’s AFL-Series ultrasensitive
low-voltage magnetic switch family:

GMR
vs. Hall Effect Demonstration
We went into the lab to demonstrate the world’s most sensitive magnetic switch—the
new AFL006—compared to a typical Hall effect sensor:
GMR is a “hall of a lot” better than Hall.
• thirty times more sensitive;
• two orders of magnitude lower power;
• omnipolar, so you don’t have to worry about magnet polarity;
and
• smaller. |
