It produces a 2bit quadrature signal which is suitable for digital systems where both magnitude and direction of adjustment must be provided. The EN series encoders are ideal for use as a digital panel control or as a position sensing device in applications where long life, reliability, high resolution and precise linearity are critical. The EN series encoder converts rotary input into electrical signals which can be used by microprocessors without A/D conversion. Typical applications include temperature control, speed control, position sensing, menu selection and volume control.
