PT10MH2.5

PT10MH2.5 Cross-Shell Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The PT10MH2.5 is a cost-effective sealed dustproof trimmer potentiometer designed with Spain’s PIHER, ACP, and other brands as benchmarks. It features a unique cross-shaped shell and a shaftless design, resulting in an extremely compact structure. With excellent dustproof and moisture-proof performance, it supports both automated SMD and through-hole assembly methods, effectively addressing the industry’s pain points of traditional shafted potentiometers—large size, easy shaft breakage during transport, and high assembly costs. Widely used in white goods, automotive electronics, power tools, and many other fields, it complies with RoHS/REACH environmental standards, achieves an IP5x dustproof rating, and maintains a failure rate of ≤50 PPM in humid environments, helping to reduce overall equipment after-sales rates by 15%.

Operating Principle

The core operating principle of the PT10MH2.5 relies on adjusting resistance values via a carbon film resistor layer. It uses a fiberglass-reinforced epoxy laminate as its base, with a carbon film resistor layer printed on the surface. Through a shaftless cross-slot or hexagonal hole structure, an external plastic knob or screwdriver drives the internal brush to rotate. As the brush slides across the carbon film resistor layer, it changes the length of the resistance path connected to the circuit, achieving precise resistance adjustment to meet the personalized resistance parameter requirements of various devices. The shaftless design eliminates the vulnerability of traditional shaft structures, while the sealed housing effectively prevents dust and moisture ingress, ensuring stable operation in complex environments.
