GT Sensors
Precision Gear Tooth and Encoder Sensors
NVE’s GT Sensor products are based on a Low Hysteresis GMR sensor material and are designed
for use in industrial speed applications where magnetic detection of gear teeth and magnetic encoder
wheels is required.
GT Sensors with both analog and digital outputs are available. The analog parts feature the large signal
and robust characteristics which NVE’s GMR materials are known for (NVE’s GMR sensors are not
damaged by extremely large magnetic fields). The sensor elements themselves are designed to provide
usable output with even the smallest gear teeth. Single and double output versions are available; the
second output is phase shifted with respect to the first, to provide quadrature for determining direction.
The digital sensors take advantage of the high
performance characteristics of GMR sensors to
provide a 50% duty cycle output with a wide
tolerance in airgap and temperature variations.
GT Sensors are available in low-profile MSOP8,
TDFN SO8, and TDFN6 packages, in order to
fit into the tightest possible spaces. An
evaluation kit is available, containing a selection
of sensors, magnets, and PCBs, so that the user
can test the parts in their application
