CA9LV10

CA9LV10 Cross-Shell Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The CA9LV10 belongs to a cost-effective sealed dustproof trimmer potentiometer series represented by Spanish brands such as PIHER and ACP. It is in the same category as PT6, PT10, PT15, CA6, CA9, and CA14. Featuring a unique cross-shaped shell and shaftless design, it boasts an extremely compact structure while delivering both dustproof performance and durability. This potentiometer covers a resistance range from 100Ω to 5MΩ, offering multiple linear resistance options of type A/B/C. Mechanical rotation angles are available in three specifications: 235±5°, 240°±5°, and 265±5°. Its mechanical life reaches up to 10,000 cycles, making it suitable for automated SMD/through-hole assembly and meeting the stringent application requirements across white goods, automotive electronics, power tools, and other fields.

Operating Principle

The CA9LV10 potentiometer uses a glass-fiber-reinforced epoxy laminate as its base, with a carbon film resistor layer printed on the surface. Through a shaftless cross-slot or hexagonal hole mechanism, an external plastic knob or screwdriver drives the internal brush to rotate, thereby changing the contact position between the brush and the carbon film resistor layer to achieve precise resistance adjustment. The shaftless design eliminates the traditional rotating shaft structure, simplifying the overall construction and fundamentally reducing the risk of shaft breakage caused by external impacts. Meanwhile, the sealed dustproof housing effectively prevents dust and moisture from entering the internal components, ensuring stable operation in harsh environments.
