TIMER AND TEMPERATURE
SELECTION
Incremental output codes are ideal for
scroll functions required for input devices.
Resistive output for temperature input
selection.
The 700 Series is the economical solution to
virtually any digital encoder or potentiometer
requirement. As the latest version in our new
generation of rotary encoder products, the 700 Series
has been freshly tooled to include resistive analog
output for potentiometer applications, as well as the
standard digital code for direct interface with a
microprocessor. The .890” package enhances the
original design concept, delivering high performance
and quality levels in the triple digit PPMs.
Electroswitch leads the market in rotational torque
management for encoders. Our process includes
digital maps to ensure repeatable and quantitative
measurement.
Newly introduced in the 700 Series in an integrated
push-button, which permits two functions in a single
shaft. This feature provides system cost savings and
user-friendly interface for input selection. The push-
button feature is offered in the same package size
as the standard 700, with a complete interface for
scrolling through a menu and making a selection.
The 700 Series features a wide range of standard
configurations to fulfill most needs. As with standard
product, customized versions for volume applications
also benefit from Electroswitch’s cost-effective,
automated production processes to build in quality
performance.
HVAC TEMPERATURE AND
FAN CONTROL
Digital or analog output for temperature
with direct drive to display and fan control
for automotive use.
ELECTRONIC RANGE CONTROL
Control of bake time, temperature and
duration in residential and commercial
applications.
PANEL INPUT DEVICE
Used to scroll through menu via shaft
rotation; for selecting menu item via push-
button.
AUDIO INPUT
Volume control for all amplifier
applications; automotive, musical, home,
and professional.

700 Series Application Notes
With the introduction of the 700 Series
Mechanical Encoder and Potentiometer,
Electroswitch delivers a low cost, multifunctional
rotary interface with repeatable torque and
‘feel’ to match the user’s needs.
The A/B code is also known as a
quadrature. In full quadrature, each change of
state in the two waveforms is counted, providing
the highest form of resolution at 4 counts per
cycle. In half quadrature, only the changes of
state in one wave form are counted, providing
2 counts per cycle. While in quarter quadrature,
only the rise in one wave form is counted,
providing 1 count per cycle.
New to the 700 Series is the addition of
resistive (analog) output. Therefore, users have
the unprecedented option of choosing
between two types of outputs; digital or resistive.
The digital outputs are available in absolute or
incremental code, and reflect Electroswitch’s
many years of technological expertise in this
area. The resistive outputs are available in 5K or
10K linear tapers; custom outputs can be
developed upon request. All of these variations
are offered in the same package size and may
be used in any combination. The typical
absolute code is either gray or binary. The four
or five bit output gray code provides the benefit
of only one bit change per change of state.
The incremental output code is known
as an A/B counting code. As the shaft is rotated,
two wave forms are generated and the A/B
code ‘counts’ these pulses, sending them to the
microprocessor to determine a ‘relative’
position. The counts or pulses continue with the
rotation of the shaft, which allows the position
to change infinitely, or as the microprocessor
allows. Direction may be determined by
analyzing the phase difference between the
two channels.
The 700 Series features 12, 16, 24, 32 or
36 mechanical detent positions that provide up
to 36 electrical outputs per revolution in
standard offering. Without mechanical detents,
the resolution per rotation can be much higher.
Electroswitch offers up to 96 electrical outputs
per revolution in this non-detented method in
custom applications.
Several options within the 700 Series
make it unique and a valuable choice for any
user. Our push-button feature allows two
functions to be controlled by one shaft. By
integrating the push-button function into its
standard design, Electroswitch has been able
to keep the package size the same for all of the
700 Series products. This push-button feature is
ideal for scrolling and select functions, or to
incorporate an on-off option in one rotary
package size.
Standard mounting configuration is shaft
perpendicular to the mounting board, with a
bracket for additional mounting strength.
