CA14 GV12.5

CA14 GV12.5 Sealed Dustproof Shaftless Trimmer Potentiometer

Product Overview

The CA14 GV12.5 belongs to a cost-effective series of sealed dustproof trimmer potentiometers, represented by Spanish brands such as PIHER and ACP. It is part of the same product family as PT6, PT10, PT15, CA6, and CA9. Featuring a cross-shaped housing and a shaftless design, this potentiometer boasts an extremely compact structure and a dustproof enclosure, effectively reducing the risk of shaft breakage caused by external impacts. It also supports both automated SMD and through-hole mounting methods, making it suitable for various production scenarios. The product complies with RoHS/REACH environmental standards, achieves an IP5x dustproof rating, and maintains a failure rate of ≤50 PPM in humid home appliance environments, helping to reduce overall after-sales service rates by 15%. It is an ideal component for white goods, automotive electronics, power tools, and other fields.

Operating Principle

The CA14 GV12.5 potentiometer uses a glass-fiber-reinforced epoxy laminate as its base substrate, with a carbon film resistor layer printed on its surface. Through a shaftless cross-slot or hexagonal socket design, an external plastic knob or screwdriver drives the internal brush to rotate, thereby adjusting the contact position between the brush and the carbon film resistor layer to achieve precise resistance adjustment. This shaftless drive design simplifies the product structure while eliminating the common issue of traditional shafted potentiometers—shaft breakage due to external impacts. Meanwhile, the sealed housing effectively prevents dust from entering, ensuring stable contact between the resistor layer and the brush, thus extending the product’s service life.
