PT10MH5

PT10MH5 Sealed Dustproof Shaftless Trimmer Potentiometer

Product Overview

The PT10MH5 is a cost-effective sealed dustproof trimmer potentiometer belonging to the product lines of Spanish brands such as PIHER and ACP. It is part of the same series as the PT6, PT10, PT15, CA6, CA9, and CA14. Featuring a cross-shaped housing and a shaftless design, it combines a compact structure with reliable performance. This potentiometer is compatible with automated SMT and through-hole assembly processes, boasts an IP5x dustproof rating, and complies with RoHS/REACH environmental standards. It can effectively withstand harsh operating conditions such as humid household appliances, with a failure rate of ≤50 PPM, helping to reduce overall after-sales service rates by 15%. It is an ideal component for white goods, automotive electronics, power tools, and other applications.

Operating Principle

The PT10MH5 potentiometer uses a fiberglass-reinforced epoxy laminate as its base, with a carbon film resistor layer printed on the surface. It eliminates the traditional shaft structure, instead employing a cross-shaped slot or an internal hexagonal hole that allows an external plastic knob or screwdriver to drive 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 not only simplifies the structure but also avoids the common issue of traditional shafts being damaged by external impacts. Meanwhile, the sealed housing effectively prevents dust from entering, ensuring long-term stable operation.
