RD161G-V1 16mm Vertical Dual Gang Rotary Potentiometer with Threaded Bushing

Product Introduction

The RD161G-V1 is a premium 16mm dual gang rotary potentiometer engineered with a threaded metal bushing and vertical PCB mounting pins. Featuring a 12.5mm shaft height, this dual-unit potentiometer delivers exceptional rotational stability and precise dual-channel signal attenuation for commercial electronics and audio control panels.

Constructed with high-grade carbon film elements and a robust metal shaft with threaded bushing, it ensures minimal tracking error matching and dependable long-term electrical performance across high-density PCB layouts.

Available for OEM mass production, this versatile component provides electronic manufacturers with exceptional circuit reliability, high rotational endurance, and flexible volume-based supply chain pricing.

Key Features

Dual Gang Stereo Architecture:

Featuring a synchronized dual-unit (gang) construction, the RD161G-V1 controls two independent audio or electrical channels simultaneously. With a tight tracking error within ±3dB, it guarantees accurate signal balance and seamless stereo channel matching across complex circuit boards.
Heavy-Duty Threaded Bushing & Shaft:

Equipped with a sturdy 16mm metal shaft and a threaded bushing (12.5mm height), this rotary potentiometer offers superior mechanical rigidity. The threaded collar allows secure panel mounting, preventing shaft deflection and protecting internal PCB solder joints from structural fatigue during heavy operation.
Smooth 300-Degree Rotational Travel:

Designed with a $300^\circ \pm 10^\circ$ total rotational angle and smooth rotational torque (20 to 200gf.cm), this component delivers fine-tuned tactile control. The balanced resistance curve provides predictable, precise voltage distribution essential for accurate audio volume adjusting and equipment calibration.
Compact Vertical PCB Mount Configuration:

The vertical pin terminal design saves valuable board real estate while maintaining strong mechanical grounding. Engineered for efficient wave soldering, the compact 12.5mm vertical profile allows high-density integration into tight industrial enclosures and modern desktop audio consoles without compromising access.
High Durability & Low Noise Signal Track:

Built for a mechanical lifecycle exceeding 10,000 cycles, the high-grade carbon track reduces operational rotational noise to under 100mV. This low-noise performance preserves signal purity, ensuring crisp audio processing and reliable parameter adjustments throughout extended industrial service.
