Product Introduction
The RA141G-H is a 14mm enclosed dual-gang rotary potentiometer designed for audio controls, electronic equipment, and PCB-mounted applications. Its insulated plastic shaft and compact horizontal structure provide reliable operation where space is limited. The dual-gang design allows two circuits to be adjusted together with one shaft.
This 14mm rotary potentiometer uses a linear taper and fixed PCB mounting terminals. The enclosed construction helps protect the internal resistance element during normal use. It supports a wide resistance range from 1KΩ to below 1MΩ, making it suitable for different circuit designs.
The RA141G-H is available with different shaft configurations and dimensions according to the RA14 series specification. Standard orders start at 3,000 pieces, with a unit price of US$0.35. Better pricing is available for larger quantities.
Key Features
1. 14mm Compact Enclosed Design
The RA141G-H uses a 14mm series construction with an enclosed body. Its compact size is suitable for electronic products where PCB space is limited. The enclosed structure also provides a practical solution for applications that require stable mechanical protection around the internal control element.
2. Dual-Gang Linear Taper
This dual-gang design combines two variable resistance sections under one shaft. Both sections can be adjusted at the same time. The linear taper makes resistance change proportional to shaft rotation, which is useful for circuit control and applications requiring coordinated adjustment of two channels.
3. Insulated Plastic Shaft
The insulated plastic shaft is designed for applications that require an electrically insulated control interface. Several shaft lengths and shaft styles are available within the RA11/RA14 series specifications, helping engineers select a suitable configuration for different panel and mechanical requirements.
4. Horizontal PCB Mounting
The RA141G-H features a horizontal mounting structure with fixed PCB terminals. This configuration allows the component to be installed directly onto a circuit board. It is suitable for compact electronic assemblies and equipment where the potentiometer needs to sit horizontally relative to the PCB.
5. Wide Resistance Range
The RA11/RA14 series supports resistance values from 1KΩ to below 1MΩ with specified resistance tolerances. The supplied technical data lists ±20% for values below 1MΩ and ±30% for the stated 1MΩ range condition, providing multiple resistance options for different circuit requirements.
6. 10,000-Cycle Rotational Life
The specified rotational life is at least 10,000 cycles. Mechanical specifications also include a total rotational angle of 300° ±10° and a rotational torque range of 20–200 gf·cm. These specifications support repeated manual adjustment in electronic control applications.
