DETENT CONFIGURATIONS
EXAMPLES
-
Stepped
potentiometers.
This innovative product family has been
specifically developed to allow the
integration of otherwise large and
expensive external mechanisms into the
body of the majority of the 10 & 15 mm.
PS/PSX/PSC/PT/PTC potentiometer series,
thus allowing a high range of
configurations: special tapers, 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).
