PT10MV10 A20K Shaftless Sealed Dustproof Trimmer Potentiometer

Product Overview

The PT10MV10 A20K belongs to a cost-effective series of sealed dustproof trimmer potentiometers represented by Spanish brands such as PIHER and ACP. This series also includes models like PT6, PT10, PT15, CA6, CA9, and CA14. Featuring a cross-shaped housing and a shaftless design, this potentiometer boasts an extremely compact structure. Paired with a dustproof enclosure, it meets stringent requirements for dust and moisture resistance. Meanwhile, the shaftless design effectively reduces the risk of shaft breakage caused by external impacts, and offers excellent compatibility with automated SMT and through-hole assembly processes, adapting to both Through-hole and SMD mounting methods. It is widely used in white goods, automotive electronics, power tools, and other fields, effectively addressing industry pain points associated with traditional shafted potentiometers—such as large size, susceptibility to shaft breakage during transport, and high assembly costs.

Operating Principle

The core operating principle of this trimmer potentiometer is based on the voltage divider circuit. A carbon film resistor layer is printed onto a fiberglass-reinforced epoxy laminate. By using a cross-shaped slot or an internal hexagonal hole without a rotating shaft, an external plastic knob or screwdriver drives the internal brush to rotate. As the brush moves along the carbon film resistor layer, the resistance value connected to the circuit changes, enabling precise adjustment of voltage, current, or signals. The shaftless drive design not only simplifies the structure but also eliminates the common issue of shaft damage found in traditional shafted potentiometers. Additionally, the sealed housing effectively prevents dust and moisture ingress, ensuring stable operation of the internal carbon film and brush.
