STEPPED OUTPUTS
Constant value zones can be combined with strategically located stops matching the flat areas of the output.

Improved repeatability
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.
Pihers detents also prevent output values from changing due to
vibration or accidental rotor movements, furthering reliable control
consistency.
PIHERs potentiometers can
feature special stepped outputs
or constant voltage zones for
the 10mm and 15mm product
families.
These constant voltage zones
can be combined with PIHERs
mechanical detents to provide
exact alignment between the
electrical output (flat areas)
and the mechanical detent
position. 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 precise control
capabilities, our 10mm and
15mm potentiometers series
are well suited for many
consumer applications such as
lighting (dimmers), power hand
tools, relays, timers and HVAC
systems.
Design tip. Cost-effectiveness
Absolute encoders can easily be
replaced connecting the potentiometer to
the microprocessors
analogue input.
Main advantages
Unique, non-overlapping values at each stop (detent position)
It prevents changes in the output value due to light vibration or accidental
rotor micro-movements
Fully customisable according to customer´s needs
Cost effective replacement for absolute encoders
