PT15NH2.5

PT15NH2.5 Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The PT15NH2.5 is a cost-effective sealed dustproof trimmer potentiometer, representative of the Spanish PIHER and ACP brands. The series includes models such as PT6, PT10, PT15, CA6, CA9, and CA14. This potentiometer features a cross-shaped housing and a shaftless design, resulting in an extremely compact structure that combines dust- and moisture-proof performance with durability. It also offers excellent compatibility with automated SMT and through-hole assembly processes, supporting both Through-hole and SMD mounting methods, making it an ideal component for white goods, automotive electronics, power tools, and other applications.

Operating Principle

The core operating principle of the PT15NH2.5 potentiometer relies on the resistance adjustment mechanism of carbon film resistors. A carbon film resistor layer is printed onto a glass-fiber-reinforced epoxy laminate. By means of an external plastic knob or screwdriver driving an internal brush via a cross-slot or hexagonal hole without a rotating shaft, precise resistance value adjustments are achieved. This shaftless drive design simplifies the structure while eliminating the risk of shaft breakage common in traditional shafted potentiometers. Meanwhile, the sealed housing effectively prevents dust and moisture ingress, ensuring stable operation under harsh environmental conditions.
