Long life versions are available under request and have the
following characteristics at Tª:
- Potentiometers with 1 to 3 detents: up to 10K cycles
- Potentiometers with 4 and more detents: up to 5K cycles
Different output voltage values can be matched at each
detent position (under request).
For the following mounting methods, the detents configurations
will be studied individually case by case:
- V02 & V21
- V12 & V22
- V18
- V24
NOTES FOR DETENTED VERSIONS:
Standard mechanical life is 500 cycles.
Detent torque can vary from 1.2 to 2.5 times the standard
potentiometer torque.
For all detents versions of more than 13 detents
the detent torque will be 0.5 to 3.5 Ncm.
Please consult your nearest Piher supplier if unique
non-overlapping values at each detent position or
LOG/ALOG tapers are required.
For more than 13 detents versions please contact your
nearest PIHER authorised distributor.

Unless otherwise
specified the detents
are evenly spaced
(using the end points
as reference)
This innovative PT´s with detents
family has been specifically developed
to allow the integration of otherwise
large and expensive external
mechanisms into the body of the
potentiometer thus allowing a high
range of configurations: special tapers,
torque, tolerances, linearity, cut track,
etc.
This detent design not only adds a
"click" sensation of position, but also
offers enormous savings in both cost
and space for any given application.
Strong and weak detents can be mixed
as per customer´s request.
Detent number and positions can be
made or fitted to the customer needs
or preferences.
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.

upon
request
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.
Design tip. Cost-effectiveness
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.
