CA14NH5 High-Cost-Performance Sealed Dustproof Shaftless Trimmer Potentiometer

Product Overview

The CA14NH5 is a high-cost-performance sealed dustproof trimmer potentiometer, representing the technology of Spanish brands such as PIHER and ACP. It belongs to the PT6, PT10, PT15, CA6, CA9, and CA14 series. Featuring a unique cross-shaped housing and a shaftless design, it boasts an extremely compact structure, offering both dust protection and resistance to external impacts. It is compatible with automated SMD mounting as well as through-hole installation, making it suitable for various industrial production scenarios. The product complies with RoHS/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 service rates by 15%. It is an ideal component for white goods, automotive electronics, power tools, and other fields.

Operating Principle

The core operating principle of the CA14NH5 trimmer potentiometer is based on the voltage divider principle. A carbon film resistor layer is printed onto a glass-fiber-reinforced epoxy laminate. Through a shaftless cross-slot or hexagonal hole mechanism, an external plastic knob or screwdriver drives the internal brush to rotate. As the brush slides along the carbon film resistor layer, it alters the length of the resistance connected to the circuit, enabling precise adjustment of resistance values to meet the fine-tuning needs of different devices for voltage, current, or signals. The shaftless drive design simplifies the structure while eliminating the risk of traditional shafts breaking under external impact, and the sealed housing effectively prevents dust from entering, ensuring stable contact between the resistor layer and the brush.
