Position indicating notch included on all LV15 rotors, except types M and P.
The Standard taper is linear (A). Log (B) and Antilog (C) tapers are also available, as well as special tapers according
to customer specifications. See an example on the application described on page 11.
Tapers
Our patented design with two wipers gives more stable electrical parameters, improved reliability and Contact Resistance Variation (CRV),
as well as narrower tolerances for detent positioning.
For potentiometers with detents, mechanical life is also 15.000 turns if no additional turns are mentioned. Please, indicate the number of
turns needed. When needing a special number of detents or matching taper, a drawing is kindly requested.
Also, there is an option of having shorter terminal tips.
By default, terminals are always straight, as shown on the “models” section. ACP can provide crimped terminals (with
snap in, “SNP” or “SNR”), to better hold the component to the PCB during the soldering operation.

Potentiometers
with detents
ACP’s patented detent (DT) feature is especially suitable for control applications where the end user will turn a knob
inserted in the potentiometer. Detents can be used to add a click feeling to the turning of the potentiometer or to control the position in
which the wiper is placed, assuring a particular output value with a narrow tolerance.
Detents can be light or strong, or even a combination of different feelings. They can be evenly distributed along the angle (standard) or
tailored to match customers’ request. They can also be combined with special tapers: constant value areas, open circuit zone, different
slopes, etc. One common example is a potentiometer with detents and matching non-overlapping voltage values in specific angular
positions, used to feed in a voltage value to a microprocessor.
