Product Introduction
The RA111G-H 11mm sealed dual-unit rotary potentiometer is designed for compact PCB applications. It uses an insulated plastic shaft and a horizontal mounting structure. The closed design helps protect the internal resistance element during assembly and normal operation.
This dual-gang potentiometer provides two independent resistance channels in one compact component. It is suitable for volume, tone, balance, and other analog control functions.
The RA111G-H is available from 3,000 pieces, with a starting price of US$0.26 per piece. Larger orders can receive better pricing. Custom options are also available for OEM projects.
Key Features
11mm Compact Design
The 11mm body helps save PCB space in compact electronic products. The horizontal mounting layout is suitable for control panels and PCB assemblies where board height is limited. It provides a practical solution for products that need two variable resistance channels in a small package.
Dual-Unit Construction
The RA111G-H integrates two potentiometer sections into one component. This dual-gang structure helps reduce component count and PCB space. It can be used for linked control functions such as stereo volume, left-right audio adjustment, and other two-channel analog circuits.
Sealed Construction
The enclosed structure helps reduce exposure of the internal element to dust, flux residue, and other contaminants during production and use. This makes the component suitable for electronic products that require a more protected rotary control structure.
Insulated Plastic Shaft
The plastic insulated shaft provides electrical isolation between the shaft and the internal electrical structure. It is suitable for applications where shaft insulation is required. Shaft length, shaft shape, and related mechanical details can be discussed for OEM projects.
PCB Mounting with Fixed Pins
The product uses PCB mounting terminals and fixed mounting pins. This structure supports stable positioning during PCB assembly. It can help simplify automated or manual mounting and reduce movement of the component during soldering.
Stable Electrical Performance
The series supports resistance values from 1kΩ to 1MΩ, depending on the selected configuration. The power rating is up to 0.05W, with a maximum operating voltage of 50V AC / 20V DC. These values support many low-power analog control circuits.

Applications
The 11mm sealed dual-unit rotary potentiometer is suitable for many compact electronic control systems. Typical applications include audio amplifiers, stereo volume controls, mixing consoles, active speakers, home audio equipment, electronic musical instruments, car audio controls, industrial control panels, test instruments, consumer electronics, and OEM control modules. Its dual-gang structure is useful when two resistance channels must be controlled from one shaft. The horizontal PCB mounting design is also suitable for compact equipment where installation height and board space are limited. Engineers can select the resistance value, taper, shaft specification, and mechanical configuration based on the circuit and panel design.
