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:
Example of 5DT with control of value in each DT.
Other examples of potentiometers with detents:
|Number of standard detents (evenly distributed) already available||1 (initial or final), 2 DT (initial and
final), 3, 4, 5, 6, 7, 8,10, 20.
|Maximum number of detents for feeling only||20|
|Maximum number of detents when the voltage value in each detent is controlled and non-overlapping||10|
Our patented design with two wipers has improved the performance of these potentiometers, giving them 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 1.000 cycles, if no additional cycles are mentioned. Please, indicate the number of cycles needed with LV (number of cycles), for example: LV07, for 7.000 cycles.
When needing a special number of detents or matching taper, a drawing is kindly requested.
