RA112G-H 11mm Horizontal Dual Unit Rotary Potentiometer with Metal Bushing

Product Introduction

The RA112G-H stands out as a dependable 11mm dual unit rotary potentiometer featuring a durable metal threaded bushing and an insulated plastic shaft. Engineers design this stereo component for compact circuit board integration, ensuring precise dual-channel resistance control and stable signal attenuation across modern electronic equipment.

Manufacturers construct these units with advanced carbon film elements inside a sealed miniature body. This design secures exceptionally smooth rotational torque, minimal electrical operating noise, and long-term signal stability. Furthermore, the horizontal right-angle pin layout combined with integrated metal support brackets attaches the component firmly to printed circuit boards.

Delivering professional manufacturing quality and attractive volume pricing, this versatile potentiometer offers global original equipment manufacturers a cost-effective solution for dual-channel audio equipment and compact industrial systems.

Key Features

• Threaded Metal Bushing Design: Engineered with a solid metal threaded collar, this potentiometer allows secure, tight panel installation. The metal bushing reinforces structural stability, preventing shaft wobble and protecting internal solder joints from mechanical stress during heavy use.

• Insulated Plastic Shaft Construction: Featuring a durable non-conductive plastic shaft, the component provides excellent electrical isolation, effectively preventing static interference and ground loops. The precise profile ensures a secure, slip-free push-on attachment for matching control knobs.

• Synchronized Dual Gang Architecture: Equipped with a dual-unit construction, the RA112G-H controls two independent audio or electrical channels simultaneously. With a tight tracking error, it guarantees accurate signal balance and seamless stereo channel matching across complex circuit boards.

• Horizontal Right-Angle PCB Mount: The horizontal pin configuration with integrated metal support brackets optimizes low-profile chassis layouts. This design reduces vertical clearance requirements, enabling efficient space management in multi-layer electronic hardware designs.

• High-Volume OEM Cost Efficiency: Available with a competitive minimum order quantity of 3,000 pieces at a direct-factory unit price of $0.26 USD, this model delivers outstanding scalability with lower production overhead and tier-based bulk discounts.
