PIHER´s potentiometers may feature
special stepped outputs or constant
voltage zones for the 10mm and
15mm product families.
These constant voltage zones can be
combined with PIHERs mechanical
detents to provide exact alignment
between the electrical output (flat
areas) and the mechanical detents
positions. The result is a higher level
of precision in controlling lighting,
temperature, motor or other
electronic control systems.
In addition to established catalogue
detent configurations, we will design
and manufacture any other
configuration on our tried-and-tested
carbon/cermet & THM/SMD
potentiometer technology and
processes.
With its exacting control capabilities,
our 10mm and 15mm potentiometers
series are well suited for many
consumer applications such as
ovens, ranges, dishwashers, lighting
(dimmers), power hand tools,
washing machines and HVAC
systems.

By combining the constant value zones with the detents, engineers
can align the same voltage values with each of the detent stops
when rotating the control both forward and backward.
This provides clear mechanical positions that are not only repeatable,
but perfectly aligned electrical outputs at each of the (detent) angles.
Piher´s detents also prevent output values from changing due to
vibration or accidental rotor movements, furthering reliable control
consistency.

DETENTS WITH CONSTANT VALUE ZONES
Constant value zones can be combined with strategically located stops matching the flat
areas of the output.
Improved repeatability
when the potentiometer´s wiper position is located at detent
nº8, the output votage will be exactly 88.9% Un
application
notes
10 stepped outputs version example:
Unique, non-overlapping values at each stop (detent position)
Prevents output value change due to light vibration or accidental rotor micro-movements
Fully customisable according to customer´s needs
Cost effective replacement for absolute encoders
Main advantages
Absolute encoders can easily be
replaced connecting the potentiometer to
the microprocessor´s
analogue input.
