Product Introduction
The RA143G-H is a 14mm dual-gang rotary potentiometer with a plastic shaft and threaded bushing. Its horizontal PCB mounting structure and fixed terminals make it suitable for compact electronic equipment. The dual-gang design allows two circuits to be controlled through one shaft.
The product uses an M9×0.75 threaded bushing for panel mounting. The shaft and bushing structure provide a practical mechanical interface for equipment panels. Its 14mm series body also helps save PCB space in compact electronic designs.
The RA143G-H supports multiple resistance values within the RA11/RA14 series range. Standard orders start at 3,000 pieces. The reference unit price is US$0.38, with better pricing available for larger quantities.
Key Features
1. 14mm Dual-Gang Structure
The RA143G-H uses a 14mm series body with two integrated resistance sections. One shaft controls both sections at the same time. This structure is useful for equipment that needs coordinated adjustment of two circuits, such as two-channel control and stereo electronic applications.
2. M9×0.75 Threaded Bushing
The potentiometer is equipped with a threaded bushing using an M9×0.75 thread. This allows the component to be secured through a suitable panel mounting hole. The bushing design provides additional mechanical support for applications that require panel-mounted control.
3. Horizontal PCB Mounting
The RA143G-H uses a horizontal mounting structure with fixed PCB terminals. The terminals are arranged for direct PCB assembly. This design can help simplify circuit-board installation while keeping the control shaft accessible from the equipment panel.
4. Plastic Shaft Construction
The product uses a plastic shaft designed for manual rotary control. The supplied series drawing shows different shaft configurations and lengths for the RA11/RA14 series. Customers can confirm the required shaft dimensions and configuration according to their equipment design.
5. Multiple Resistance Options
The RA11/RA14 series supports resistance values from 1KΩ to below 1MΩ, with the specified tolerance conditions shown in the technical data. This gives engineers several resistance options when selecting a suitable component for an electronic circuit.
6. Rated for 10,000 Cycles
The supplied technical specification lists a rotational life of at least 10,000 cycles. The mechanical specification also gives a total rotational angle of 300° ±10° and rotational torque of 20–200 gf·cm, supporting repeated manual adjustment.

Customization Options
The RA143G-H is part of the RA11/RA14 insulated-shaft rotary potentiometer series. The supplied drawings show different shaft configurations and shaft lengths. Engineers can select the appropriate mechanical configuration based on panel depth, knob design, and PCB layout requirements.
For OEM and ODM projects, customers can confirm the required resistance value, shaft length, shaft style, mounting dimensions, and electrical requirements before production.
The RA143G-H drawing also specifies the M9×0.75 bushing. Customers should check the panel mounting hole and PCB mounting dimensions against the product drawing before placing a production order.
For volume projects, technical requirements can be reviewed before mass production to reduce assembly and compatibility risks.
Applications
The RA143G-H can be used in electronic equipment that requires dual-channel rotary adjustment and panel mounting. Typical applications include stereo audio equipment, audio amplifiers, speaker systems, mixing equipment, electronic instruments, control panels, consumer electronics, PCB control assemblies, industrial electronic equipment, and compact control devices. The dual-gang structure allows two circuits to be adjusted through one shaft. The horizontal PCB structure is suitable for circuit boards where the control component is mounted parallel to the board. The M9×0.75 threaded bushing also provides a practical solution for panel-mounted control applications.
