 Image is representative only | | A self-contained, incremental, rotary optical device that produces a 2-bit quadrature signal output that is suitable for digital systems that require both magnitude and direction of adjustment data. The device converts rotary input into digital output signals that can be used directly, without the need for analogue to digital conversion. The output signals are 90° phase shifted square waves that do not require the debounce circuitry that a mechanical type of device requires. The benefits of these features make it possible to reduce component count, circuit complexity, cost and also to increase oerformance and reliability. Having a long life of 10,000,000 shaft revolutions and a compact, rugged body make this encoder suitable for use in extended service and limited space applications as a digital panel control or position sensing device.
