Rotary Encoder Optical 128 Cycles per Revolution 1/8" Round Shaft

The self-contained rotary optical encoder produces a 2-bit quadrature signal which is suitable for digital systems where both magnitude and direction of adjustment must be provided. This encoder is 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 encoder converts rotary input into electrical signals which can be used by microprocessors without ADC. The output signals are square wave digital pulses which do not require debounce circuitry.
