Precision Gear Tooth and Encoder Sensors

NVEs 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 NVEs GMR materials are known for (NVEs 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
