EN - Rotary Optical Encoder
GENERAL INFORMATION
The Bourns
EN model is a self-contained rotary optical encoder. It
produces a 2-bit quadrature signal which is suitable for digital systems
where both magnitude and direction of adjustment must be provided.
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.
The EN series encoder converts rotary input into electrical signals
which can be used by microprocessors without A/D conversion.
Bourns encoder output signals are square wave digital pulses which do
not require debounce circuitry. Both features make it possible to
significantly reduce the memory overhead, wiring and wiring
interconnects required by other types of control devices.
EN optical encoders offer a useful rotational life of from 10 million to
200 million shaft revolutions, making them ideal for extended service
applications. The Bourns encoder is also compact and well suited for
situations where the available space is limited.
