PT15GV15

PT15GV15 Cross-Shell Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The PT15GV15 is a cost-effective sealed dustproof trimmer potentiometer, representing technologies from Spanish brands such as PIHER and ACP. It features a cross-shaped housing and a shaftless design, combining compact structure with stable performance. Based on the technical principle of printing a carbon film resistor layer onto a glass-fiber-reinforced epoxy laminate, this product uses an external plastic knob or screwdriver to drive a cross-slot or hexagonal socket, rotating the internal brush to adjust resistance values. It is compatible with automated SMT and through-hole/SMD assembly processes, achieves an IP5x dustproof rating, complies with RoHS/REACH environmental standards, and is widely used in white goods, automotive electronics, power tools, and other fields.

Technical Principle

The core operating principle of the PT15GV15 revolves around the interaction between the carbon film resistor layer and the brush: a uniform carbon film resistor layer is printed on the surface of a glass-fiber-reinforced epoxy laminate, forming a stable foundation for resistance adjustment. The product abandons the traditional shaft-based design, adopting a shaftless cross-slot or hexagonal socket structure. An external plastic knob or screwdriver applies force to rotate the internal brush across the carbon film resistor layer, altering the contact position between the brush and the resistor layer to achieve precise resistance regulation. This shaftless drive design not only avoids the risk of shaft breakage but also simplifies external actuation, meeting the requirements of automated assembly processes.
