CA14 NV15

CA14 NV15 Cross-Shell Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The CA14 NV15 belongs to a cost-effective sealed dustproof trimmer potentiometer series represented by Spanish brands such as PIHER and ACP. Featuring a cross-shaped shell and shaftless design, it combines a compact structure with excellent dustproof performance. This potentiometer covers a resistance range from 100Ω to 5MΩ, offering multiple linear resistance options in A/B/C types. Mechanical rotation angles are available in three specifications: 235±5°, 240°±5°, and 265±5°. It can withstand 10,000 mechanical rotations, achieves an IP5x dustproof rating, complies with RoHS/REACH environmental standards, and exhibits a failure rate of ≤50PPM in humid home appliance environments. It helps reduce the overall after-sales rate by 15%, is compatible with automated through-hole/SMD mounting processes, and is an ideal component choice for white goods, automotive electronics, power tools, and other fields.

Operating Principle

The core operating principle of the CA14 NV15 potentiometer is based on brush contact adjustment within a carbon film resistor layer: a carbon film resistor layer is printed onto a glass-fiber-reinforced epoxy laminate. Using a shaftless cross-slot or hexagonal hole structure, an external plastic knob or screwdriver drives the internal brush to rotate, altering the contact position between the brush and the carbon film resistor layer, thereby achieving precise resistance adjustment to meet voltage and current control requirements in various circuits. The shaftless drive design simplifies the structure while eliminating the risk of shaft breakage common in traditional shafted potentiometers.
