PT10GH5

PT10GH5 Cross-Shell Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The PT10GH5 belongs to a cost-effective sealed dustproof trimmer potentiometer series represented by Spanish brands such as PIHER and ACP, and is classified alongside the PT6, PT10, PT15, CA6, CA9, and CA14. It features a unique cross-shaped shell and a shaftless design, resulting in an extremely compact structure with excellent dustproof performance. This not only reduces the risk of shaft breakage caused by external impacts but also offers outstanding compatibility with automated SMT and through-hole assembly processes, supporting both Through-hole and SMD mounting methods. It meets the stringent requirements of various fields, including white goods, automotive electronics, and power tools, while complying with RoHS/REACH environmental standards. With an IP5x dustproof rating and a failure rate of ≤50 PPM in humid environments, it effectively lowers overall after-sales service rates.

Operating Principle

The core operation of the PT10GH5 is based on the principle of voltage division using resistors. It employs a fiberglass-reinforced epoxy laminate substrate with a carbon film resistor layer printed on its surface. Unlike traditional shafted potentiometers, it lacks a rotating shaft; instead, an external plastic knob or screwdriver drives a cross-slot or hexagonal socket, causing the internal brush to rotate along the carbon film resistor layer. This changes the contact position of the brush, enabling precise adjustment of resistance values. This shaftless drive design simplifies the structure, eliminates the vulnerability of conventional shafts to external damage, and ensures stable contact between the carbon film and the brush through the sealed housing, thereby extending the product’s service life.
