SD1009N-H 100mm Dual Unit Slide Potentiometer with Dual Rail Design

Product Introduction

The SD1009N-H is a high-performance 100mm dual unit slide potentiometer engineered for professional audio mixing consoles and control systems. Featuring a rugged dual rail architecture, this premium fader ensures perfectly synchronized channel tracking and ultra-smooth linear attenuation for demanding commercial electronic and industrial systems.

Built with an integrated dustproof felt cloth barrier, the internal carbon tracks remain securely shielded from environmental debris. This premium protection design significantly extends component lifespan while maintaining pristine signal clarity.

Offering global OEMs an outstanding balance of mechanical durability and precise electrical control, this 127mm metal case potentiometer provides a reliable high-volume wholesale manufacturing solution.

Key Features

• Dual Rail Precision Guidance:

  Engineered with a high-grade dual rail structure, this 100mm fader delivers ultra-stable slide performance with minimal lateral play. The parallel rails distribute operational force evenly, eliminating lever wobble and ensuring a premium tactile feel required by professional sound engineers and calibration technicians.

• Advanced Dustproof Protection:

  Featuring an integrated heavy-duty dustproof felt cloth strip, the slider mechanism is protected against dust, lint, and liquid splashes. This protective barrier preserves internal carbon track integrity, eliminates unwanted sliding noise, and guarantees high reliability in harsh, high-traffic commercial environments.

• Synchronized Dual Unit Configuration:

  Designed as a G-type dual-unit/stereo gang potentiometer, it controls two independent circuit channels simultaneously. This layout ensures tight tracking error matching within ±3dB, making it an ideal choice for high-fidelity stereo audio attenuation, balanced audio systems, and multi-channel industrial automation controls.

• Rugged Metal Case Shell:

  Housed in a rigid metal casing measuring 127mm × 16mm × 10.2mm, this component offers exceptional mechanical protection and superior electromagnetic interference shielding. The reinforced structural envelope withstands up to 5kgf.cm of shaft stop strength, protecting critical internal components from stress.

• Optimized B2B Supply Economics:

  With a competitive unit price of $2.20 USD and a direct-factory MOQ of 2,000 pieces, this model offers premium value. We provide comprehensive scalability with scalable volume discounts and highly flexible OEM/ODM modifications for custom resistance tapers, lever lengths, and mounting pin configurations.
