CA9 MV11

CA9 MV11 Sealed Dustproof Shaftless Trimmer Potentiometer

Product Overview

The CA9 MV11 is a cost-effective sealed dustproof trimmer potentiometer designed with Spain’s PIHER and ACP brands as benchmarks. Featuring a cross-shaped housing and an innovative shaftless design, it combines a compact structure with excellent dustproof performance. The potentiometer covers a resistance range of 100Ω to 5MΩ, offering linear types A/B/C, and provides selectable mechanical rotation angles of 235±5°, 240°±5°, or 265±5°, meeting the adjustment needs of various applications. Certified compliant with RoHS and REACH, it achieves an IP5x dustproof rating, with a failure rate of ≤50PPM in humid home appliance environments, effectively reducing overall after-sales service rates by 15%. It also supports automated SMD and through-hole assembly processes, enhancing assembly efficiency, making it an ideal component for white goods, automotive electronics, power tools, and other fields.

Technical Principle

The CA9 MV11 potentiometer operates on the principle of carbon film resistor adjustment. Its core structure uses a glass-fiber-reinforced epoxy laminate as the base, with a carbon film resistor layer printed on the surface. By means of a cross-slot or hexagonal hole without a rotating shaft, an external plastic knob or screwdriver drives the internal brush to rotate, achieving precise resistance value adjustment. The shaftless design eliminates the protruding shaft found in traditional potentiometers, thereby avoiding the risk of shaft breakage due to external impacts and making the overall structure more compact. Combined with a sealed dustproof housing, it effectively prevents dust and moisture ingress, ensuring stable operation in humid and dusty environments.
