The NVE ABL004-00E analog gear tooth sensors are versatile, wide airgap typically used with ferromagnetic gears and bias magnets. The sensor elements are spaced at 1mm for use with a recommended gear pitch of between 2.5mm and 6mm and an operating frequency of 1MHz. The ABL004 series from NVE have differential sensor elements that provide sinusoidal outputs and is a single bridge sensor producing a sinusoidal wave form at the output.
