PT15LV17.5

PT15LV17.5 Spanish-Style Sealed Dustproof Shaftless Trimmer Potentiometer

Product Overview

The PT15LV17.5 is a cost-effective sealed dustproof trimmer potentiometer designed with reference to Spanish brands such as PIHER and ACP. It features a cross-shaped housing and a shaftless design, combining a compact structure with excellent durability. This potentiometer covers a resistance range from 100Ω to 5MΩ and supports multiple linear resistance types—A, B, and C. Mechanical rotation angles are available in 235±5°, 240°±5°, and 265±5° options, meeting the adjustment needs of various applications. The product complies with RoHS and REACH environmental standards, achieves an IP5x dustproof rating, and maintains a failure rate of ≤50PPM in humid home appliance environments, effectively reducing overall after-sales service rates. It is an ideal component for white goods, automotive electronics, power tools, and other fields.

Operating Principle

The PT15LV17.5 potentiometer uses a glass-fiber-reinforced epoxy laminate as its base substrate, with a carbon film resistor layer printed on the surface. Its core adjustment mechanism adopts a cross-slot/inner hexagonal hole design without a rotating shaft, driven by an external plastic knob or screwdriver to rotate the internal brush. By moving the brush across the carbon film resistor layer, precise resistance adjustment is achieved. This shaftless drive design simplifies the structure while eliminating the common issue of traditional shafted potentiometers breaking their shafts under external impact. Meanwhile, the sealed dustproof housing effectively prevents dust and moisture ingress, ensuring stable operation even in harsh environments.
