PT10LV10 Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The PT10LV10 is a cost-effective sealed dustproof trimmer potentiometer, representing brands such as Spain’s PIHER and ACP. It belongs to the PT6, PT10, PT15, CA6, CA9, and CA14 series, featuring a cross-shaped housing and a shaftless design that combines compactness with reliable performance. The product offers a resistance range from 100Ω to 5MΩ, with multiple linear resistance options in A/B/C types. Mechanical rotation angles are available in three specifications: 235°±5°, 240°±5°, and 265°±5°. Its mechanical life reaches up to 10,000 cycles, and it supports both automated SMD and through-hole mounting methods, meeting assembly requirements across various industries. Additionally, it complies with RoHS/REACH environmental standards, achieves an IP5x dustproof rating, and maintains a failure rate of ≤50 PPM in humid environments, effectively reducing overall after-sales service rates.

Operating Principle

The core operation of the PT10LV10 potentiometer relies on the interaction between a carbon film resistor layer and a brush: a carbon film resistor layer is printed onto a glass-fiber-reinforced epoxy laminate. Through a shaftless cross-slot or hexagonal hole structure, an external plastic knob or screwdriver drives the internal brush to rotate, altering the contact position between the brush and the carbon film resistor layer, thereby precisely adjusting the resistance value to meet dynamic circuit requirements. The shaftless drive design simplifies the structure while eliminating the risk of shaft breakage common in traditional shafted potentiometers, making it ideal for applications involving frequent long-term adjustments.
