Thumbwheels
• CA9. Thumbwheels are available in different colors. On request,
they can also be provided in accordance with UL 94 V-0.
Potentiometers can be supplied with thumbwheels already inserted
in. ACP can also study special requests for thumbwheels.

Potentiometers with detents
ACP’s “detent” feature (DT) is specially suitable for control applications. Our patented design has improved the features of these poten-
tiometers:
- Longer mechanical life: up to 10.000 cycles.
- More stable electrical parameters.
- Improved reliability and Contact Resistance Variation (CRV).
- Narrower tolerances for detent positioning.
Detents can be lighter or stronger, or even a combination of both feelings. Detents 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, different slopes, etc.
Examples: 4, 6 and 20 detents –evenly distributed–.

Terminals
By default, terminals are always straight for the 9mm size, as shown on the “models” menu.
ACP can provide crimped terminals (with “snap in”), to better hold the component to the board prior to soldering.
