NVE GT Sensors are designed for detection of gear teeth and magnetic encoder
wheels in industrial speed sensing. The digital sensors use high-sensitivity,
| GT Sensor Tips (02:28)|
GMR to detect even the smallest gear teeth and to provide a
50% duty cycle output with wide airgap and temperature tolerances. Unlike
other magnetic sensing technologies, NVE's GMR sensors withstand extremely
large magnetic fields.
GT Sensors are available with analog or digital outputs. Dual-output versions
are available with the second output phase shifted with respect to the first
for quadrature to determine direction.
Low profile MSOP8, TDFN SO8, and TDFN6 packages allow GT Sensors to fit in
the tightest spaces. An evaluation
kit is available with a variety of sensors, magnets, and PCBs.
