CA14 GV17.5

CA14 GV17.5 Cross-Shell Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The CA14 GV17.5 is a cost-effective sealed dustproof trimmer potentiometer designed with Spain’s PIHER and ACP brands as benchmarks. Featuring a cross-shaped shell and a shaftless design, it boasts an extremely compact structure while offering both dust protection and ease of assembly. The product covers a resistance range from 100Ω to 5MΩ, available in three linear resistance types—A, B, and C—and comes in three mechanical rotation angle options: 235°±5°, 240°±5°, and 265°±5°. With a mechanical life of up to 10,000 cycles, it 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 the overall after-sales rate by 15%, making it suitable for precision adjustment needs across white goods, automotive electronics, power tools, and other fields.

Operating Principle

The CA14 GV17.5 potentiometer uses a glass-fiber-reinforced epoxy laminate as its base, with a carbon film resistor layer printed on the surface. It abandons the traditional shaft structure, instead driving the internal brush via an external plastic knob or screwdriver that engages with a cross-slot or hexagonal socket, enabling precise adjustment of resistance values. The shaftless drive design not only simplifies the structure but also eliminates the risk of shaft breakage caused by external impacts. Meanwhile, the sealed dustproof housing effectively prevents dust and moisture ingress, ensuring stable contact between the carbon film resistor layer and the brush, thereby extending the product’s service life in challenging environments.
