CA6 KV SMD

CA6 KV SMD Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The CA6 KV SMD belongs to the high-cost-performance sealed dustproof trimmer potentiometer series represented by Spain’s PIHER and ACP brands. Along with PT6, PT10, PT15, CA9, and CA14, it forms part of this product line. Featuring a cross-shaped housing and a shaftless design, it combines a compact structure with excellent dustproof performance. The product supports automated SMD mounting processes, offers resistance values ranging from 100Ω to 5MΩ, and provides three types of linear resistance—A, B, and C—for flexible selection. Mechanical rotation angles are available in three specifications: 235°±5°, 240°±5°, and 265°±5°. With a mechanical life of up to 10,000 cycles, it fully complies with RoHS/REACH environmental standards, achieves an IP5x dustproof rating, and maintains a failure rate of ≤50 PPM in humid environments. This effectively reduces overall after-sales service rates by 15%, making it an ideal component for white goods, automotive electronics, power tools, and other applications.

Operating Principle

The CA6 KV SMD potentiometer uses a glass-fiber-reinforced epoxy laminate as its base, with a carbon film resistor layer printed on its surface. Through a shaftless cross-slot mechanism—driven by an external plastic knob or screwdriver—it rotates the internal brush, thereby adjusting the contact position between the brush and the carbon film resistor layer to achieve precise resistance adjustment. The shaftless design eliminates the protruding shaft found in traditional potentiometers, fundamentally preventing shaft breakage caused by external impacts. Meanwhile, the sealed dustproof housing effectively blocks dust and moisture from entering the internal resistor structure, ensuring stable operation even in harsh environments.
