GT Sensor™ Precision Gear Tooth Sensors
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.
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, and a
demonstrator allows you to experiment with a sensor-gear airgap.

GT Sensor Tips
ABL and AKL-Series sensors are versatile, wide air gap gear-tooth sensors. The
sensors are used with ferromagnetic gears and bias magnets, or with magnetic encoders.
ABL-Series analog sensors have differential sensor
elements that provide sinusoidal outputs. Three standard spacings are available
for use with fine and coarse pitches. Single- or double-bridge configurations
are available. Double bridges generate sine and cosine outputs to provide direction
information:

AKL-Series digital sensors are configured as two-wire devices, where the supply current indicates a passing tooth. Three AKL-Series parts are available: the AKL001-12 is designed for gear teeth or encoders with a pitch of 2.5 to 6 mm, the AKL002-12 for a pitch of 1 to 2.5 mm, and the AKL003-12 for a pitch of 0.6 to 1.5 mm:
