DETENT CONFIGURATIONS
EXAMPLES
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, 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 cutomer´s request.
Detent number and positions can be made
or fitted to the customer needs or
preferences.

Detent torque can vary from 1.2 to 2.5 times the standard
potentiometer torque.
following characteristics at Tª:
- Potentiometers with 1 to 3 detents: up to 10K cycles
- Potentiometers with 4 and more detents:
up to 5K cycles
non-overlapping values at each detent position or
LOG/ALOG tapers are required.
(6)
Different output voltage values can be matched at each
detent position (under request).

Our potentiometers can feature flatted regions in its output curve. This allows engineers to precisely control
constant voltage outputs within the normal rotational range of their potentiometer.
These regions can be combined with Pihers detent feature providing a positive mechanical action when
rotating the potentiometer into these constant voltage zones.
