PT6 KH

PT6 KH Cross-Shell Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The PT6 KH is a cost-effective sealed dustproof trimmer potentiometer designed with Spain’s PIHER and ACP brands as benchmarks. It features a unique cross-shaped housing and a shaftless design, resulting in an extremely compact structure while delivering excellent dustproof performance and resistance to external damage. This potentiometer supports automated SMT/through-hole assembly processes, making it suitable for various production scenarios. Its resistance range spans from 100 Ω to 5 MΩ, offering A/B/C linear resistance options, and its mechanical rotation angle can be customized to meet different operating requirements. With a service life of up to 10,000 cycles, it complies with RoHS and REACH environmental standards, achieves an IP5x dustproof rating, and exhibits a failure rate of ≤50 PPM in humid home appliance environments, effectively reducing overall after-sales costs. It is an ideal component for white goods, automotive electronics, power tools, and other fields.

Operating Principle

The PT6 KH 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 mechanism, an external plastic knob or screwdriver drives the internal brush to rotate, enabling precise adjustment of resistance values. This shaftless drive design eliminates the protruding shaft found in traditional potentiometers, simplifying the structure and fundamentally reducing the risk of shaft breakage caused by external impacts. Meanwhile, the sealed dustproof housing effectively prevents dust and moisture ingress, ensuring stable operation even in harsh environments.
