PT10 KH10 A10K Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The PT10 KH10 A10K belongs to a cost-effective sealed dustproof trimmer potentiometer series represented by Spanish brands such as PIHER and ACP. This series also includes models like PT6, PT15, CA6, CA9, and CA14. The product features a cross-shaped housing and a shaftless design, making it extremely compact while offering excellent dust- and moisture-proof performance and resistance to external impacts. It is fully compatible with automated SMD and through-hole assembly processes, effectively reducing assembly costs, making it an ideal component for white goods, automotive electronics, power tools, and other fields.

Operating Principle

This potentiometer uses a glass-fiber-reinforced epoxy laminate as its base substrate, with a carbon film resistor layer printed on its surface. Through a shaftless cross-slot or hexagonal hole structure, an external plastic knob or screwdriver drives the internal brush to rotate, thereby changing the contact position between the brush and the carbon film resistor layer to achieve precise resistance adjustment. The shaftless design eliminates the protruding shaft found in traditional potentiometers, fundamentally preventing shaft breakage caused by external impacts. Meanwhile, the sealed housing effectively blocks dust and moisture ingress, ensuring stable operation in harsh environments.
