PT10GH2.5

PT10GH2.5 Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

PT10GH2.5 belongs to the high-cost-performance sealed dustproof trimmer potentiometer series represented by Spanish brands such as PIHER and ACP. Along with PT6, PT10, PT15, CA6, CA9, and CA14, it is part of this series. Featuring a unique cross-shaped housing and a shaftless design, it boasts an extremely compact structure, excellent dust- and moisture-proof performance, and outstanding durability. It is highly compatible with both automated SMD and through-hole assembly processes, effectively meeting the stringent requirements of white goods, automotive electronics, power tools, and other fields. Compliant with RoHS and REACH environmental standards, it achieves an IP5x dustproof rating, with a failure rate of ≤50 PPM in humid appliance environments, helping to reduce overall after-sales service rates by 15%.

Operating Principle

The PT10GH2.5 potentiometer uses a fiberglass-reinforced epoxy laminate as its base, with a carbon film resistor layer printed on the surface. Abandoning the traditional shaft structure, it adopts a shaftless cross-slot design driven by an external plastic knob or screwdriver to rotate the internal brush. By changing the contact position between the brush and the carbon film resistor layer, precise resistance adjustment is achieved. This shaftless drive method not only simplifies the product structure but also eliminates the risk of shaft breakage caused by external impacts—a common issue with conventional shafted potentiometers. Meanwhile, the sealed dustproof housing effectively prevents dust and moisture from entering, ensuring stable operation of the internal carbon film resistor layer and brush.
