The NVE AKL003-12E analog gear tooth sensors are versatile, wide airgap typically used with ferromagnetic gears and bias magnets. The sensor elements are spaced at 0.3mm for use with a recommended gear pitch between 0.6mm and 1.5mm with an operating frequency up to 10kHz. The AKL-series sensors from NVE combine a sensor bridge with integrated signal processing to provide a 50% duty cycle digital output. Integrated signal processing includes gain and offset normalization. AKL-Series sensors are configured as two wire devices, where the supply current indicates passing teeth.
