CA6KV

CA6KV Sealed Dustproof Shaftless Trimmer Potentiometer

Product Overview

The CA6KV is a cost-effective sealed dustproof trimmer potentiometer, with technology represented by Spanish brands such as PIHER and ACP. It features a cross-shaped housing and a shaftless design, combining a compact structure with excellent dustproof performance. This potentiometer covers a resistance range of 100Ω to 5MΩ, offering three linear resistance options—A, B, and C—and comes in three mechanical rotation angle specifications: 235°±5°, 240°±5°, and 265°±5°. With a mechanical life of up to 10,000 cycles, it supports both automated SMD and through-hole mounting methods, fully complies with RoHS/REACH environmental standards, achieves an IP5x dustproof rating, and maintains a failure rate of ≤50 PPM in humid home appliance environments. It can effectively reduce the overall after-sales failure rate by 15%, making it an ideal component for white goods, automotive electronics, power tools, and other fields.

Operating Principle

The core operating principle of the CA6KV potentiometer is based on adjusting resistance using carbon film resistors. A carbon film resistor layer is printed onto a glass-fiber-reinforced epoxy laminate, and via a shaftless cross-slot or hexagonal socket mechanism, an external plastic knob or screwdriver drives an 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 protruding shaft found in traditional potentiometers, simplifying the drive mechanism while fundamentally preventing the risk of shaft breakage due to external impacts. Meanwhile, the sealed housing effectively blocks dust from entering, ensuring stable and accurate resistance regulation.
