The EN series encoder converts rotary input into electrical signals which can be used by microprocessors without A/D conversion.
Encoder output signals are square wave digital pulses which do not require debounce circuitry.
The EN 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.
