RA093N-H 9mm Rotary Potentiometer with Threaded Bushing and Horizontal Pins

Product Introduction

The RA093N-H is a high-performance 9mm rotary potentiometer featuring a robust metal threaded bushing and an insulated plastic shaft. Built for precision circuit board integration, this single-unit component delivers accurate resistance control and reliable signal attenuation across compact electronic devices.

Engineered with advanced carbon film elements inside a fully enclosed miniature housing, it ensures exceptionally smooth rotational torque, minimal electrical noise, and long-term operating stability. The horizontal right-angle pin layout combined with integrated mounting brackets secures firm attachment to circuit boards.

Offering reliable manufacturing quality and attractive volume pricing, this versatile potentiometer gives global OEMs a cost-effective solution for professional audio and industrial control systems.

Key Features

Threaded Metal Bushing Design:

Equipped with a solid M9 threaded metal 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, preventing static interference and ground loops. The precise spline profile ensures a secure, slip-free push-on attachment for matching control knobs.
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.
Smooth 280-Degree Rotational Travel:

Featuring a wide $280^\circ \pm 10^\circ$ total rotational angle and balanced operational torque (10 to 100 gf.cm), the device ensures fine tactile control. The predictable resistance curve allows accurate, repeatable voltage division.
High-Volume OEM Cost Efficiency:

Available with a competitive MOQ of 5,000 pieces at a direct-factory unit price of $0.18 USD, this model delivers outstanding scalability with lower production overhead and tier-based bulk discounts.
