CA9 MV10

CA9 MV10 Cross-Shell Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The CA9 MV10 belongs to the high-cost-performance sealed dustproof trimmer potentiometer series represented by Spanish brands such as PIHER and ACP, and is in the same category as PT6, PT10, PT15, CA6, and CA14. The product features a unique cross-shaped shell and a shaftless design, combining a compact structure with excellent dustproof performance. It supports both automated SMD and through-hole assembly methods, and is widely used in white goods, automotive electronics, power tools, and other fields, meeting the demanding requirements of industrial and home appliance environments.

Operating Principle

The CA9 MV10 potentiometer uses a glass-fiber-reinforced epoxy laminate as its base substrate, with a carbon film resistor layer printed on its surface. Through a cross-slot or an internal hexagonal hole without a rotating shaft, 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 drive design simplifies the structure while eliminating the fracture risk associated with traditional shafts, and the sealed housing effectively prevents external dust and moisture from entering, ensuring long-term stable operation of the potentiometer.
