GENERAL INFORMATION
The Bourns
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.
systems where both magnitude and direction of adjustment must

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.
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 signifi cantly reduce the memory overhead, wiring and wiring inter-
connects required by other types of control devices.

connects 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.
