Product Introduction
The RB161G-H is a 16mm dual-gang rotary potentiometer with a plastic shaft, horizontal mounting structure, and support bracket. It is designed for compact electronic equipment that needs two circuits to be adjusted together. Its dual-gang design lets one shaft control both resistance sections. The horizontal structure helps fit applications where PCB space and shaft direction are important.
The RB16 series supports a 300° ±10° total rotational angle and 20–200 gf·cm rotational torque. It also features a center click position and a specified rotational life of at least 10,000 cycles.
The RB161G-H is suitable for OEM and ODM projects. MOQ starts at 3,000 pieces. The reference unit price is US$0.18, with better pricing available for larger quantities.
Key Features
1. 16mm Dual-Gang Design
The RB161G-H uses a 16mm body with two resistance sections operated by one shaft. This allows two related circuits to be adjusted at the same time. It is useful for stereo control, dual-channel adjustment, and other electronic designs that need synchronized rotary operation from a single control.
2. Plastic Shaft Construction
The RB161G-H uses an insulated plastic shaft for manual rotary control. The shaft design is suitable for electronic equipment that requires an insulated operating interface. Different shaft configurations are available within the RB16 series, allowing engineers to select a suitable mechanical option for their assembly.
3. Horizontal Mounting Structure
This model is designed for horizontal PCB mounting with a support bracket. The mounting structure positions the potentiometer body parallel to the PCB while keeping the shaft available for external control. This can be useful in compact equipment where the available PCB and panel space require a horizontal component layout.
4. Center Click Position
The RB16 series specification lists a center click position with a rotational torque of 20–200 gf·cm. The click provides a clear tactile reference during adjustment. This feature can help users locate the center position when operating equipment manually, depending on the circuit and control requirements.
5. Multiple Resistance Options
The RB16 series supports resistance values from 1KΩ to below 1MΩ under the specified tolerance conditions. This gives engineers a range of resistance choices for different circuit designs. Resistance taper options are also specified by the series documentation and should be confirmed for each project.
6. 10,000-Cycle Rotational Life
The RB16 series has a specified rotational life of at least 10,000 cycles. Its mechanical specification includes a total rotational angle of 300° ±10°, shaft stop strength of ≤6 kgf·cm, and push-and-pull strength of ≥5 kgf·cm.

Customization Options
The RB161G-H belongs to the RB16 insulated-shaft series. The supplied drawings show different shaft types and shaft lengths. Customers can select a suitable shaft configuration according to the panel structure, knob design, and available installation space.
For OEM and ODM projects, customers can confirm the resistance value, resistance taper, shaft length, shaft style, mounting dimensions, and PCB layout before production.
The horizontal mounting structure and support bracket should be checked against the customer’s PCB design. Providing a PCB drawing or mechanical drawing can help engineers confirm compatibility before mass production.
For larger orders, project-specific requirements can be reviewed during the engineering stage.
Applications
The RB161G-H is designed for electronic equipment that requires dual-channel rotary adjustment. Typical applications include stereo audio equipment, audio amplifiers, speaker systems, mixing equipment, electronic instruments, control panels, consumer electronics, home audio products, PCB control boards, industrial electronic equipment, and compact control devices. Its dual-gang construction lets one shaft operate two resistance sections together. The horizontal PCB structure can help fit equipment with specific board layouts. The plastic shaft provides an insulated control interface for manual adjustment. Its 16mm series size offers a practical option for projects requiring a larger rotary component than compact 12mm designs.
