PT10 MV10 10 Positioning

Product Overview

PT10 is a cost-effective, sealed, dustproof trimmer potentiometer, representative of Spanish brands such as PIHER and ACP. It features a cross-shaped housing and a shaftless design, resulting in an extremely compact structure that combines dustproof, moisture-proof, and impact-resistant properties. Compatible with both automated SMD and through-hole mounting methods, it is widely used in white goods, automotive electronics, power tools, and other fields, meeting the demanding requirements of industrial environments. The product complies with RoHS/REACH environmental standards, achieves an IP5x dustproof rating, and maintains a failure rate of ≤50 PPM in humid conditions, effectively reducing overall after-sales service rates by 15%.

Operating Principle

The core operating principle of the PT10 trimmer potentiometer is based on the brush adjustment mechanism of a carbon film resistor layer: a carbon film resistor layer is printed onto a glass-fiber-reinforced epoxy laminate. Using a cross-slot or hexagonal socket without a rotating shaft, 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. 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.
