PT15NH5

PT15NH5 Cross-Shell Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

PT15NH5 is a cost-effective sealed dustproof trimmer potentiometer, comparable to brands such as Spain’s PIHER and ACP. It features a cross-shaped shell and a shaftless design, resulting in an extremely compact structure that combines dustproof protection with flexible installation compatibility. The product supports automated SMT and through-hole assembly, offering excellent compatibility and effectively adapting to various production and assembly scenarios. It also complies with RoHS and REACH environmental standards, achieves an IP5x dustproof rating, and maintains a failure rate of ≤50 PPM in humid home appliance environments, helping reduce overall after-sales service rates by 15%. It is an ideal component for white goods, automotive electronics, power tools, and other fields.

Operating Principle

PT15NH5 operates on the principle of potentiometric adjustment using a carbon film resistor layer. 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, thereby changing the contact position between the brush and the carbon film resistor layer to achieve precise resistance adjustment. The shaftless drive design simplifies the product structure while eliminating the risk of shaft breakage common in traditional shafted potentiometers. Meanwhile, the sealed dustproof housing effectively prevents dust from entering, ensuring stable operation even in complex environments.
