multi-gang rotary potentiometer

used in audio equipment and various electronic devices.

linear potentiometer

Linear potentiometers (also known as slide potentiometers or faders) are widely used for audio mixing console faders, motor control, and industrial speed regulation systems. Featuring smooth linear motion, adjustable resistance, and exceptionally long life (up to one million cycles or more), these potentiometers are ideal for real-time sound level control, channel balancing, automated audio mixing, and precise motor speed adjustment. Motorized linear potentiometers provide remote and programmable adjustment, supporting both advanced digital mixing consoles and automated industrial machinery. Customization options—including resistance values, travel length, and mechanical configuration—are available to meet the specific requirements of audio, motorized, and industrial applications.

trimmer potentiometer

Miniature potentiometers are compact adjustable resistors designed for precise control in limited spaces. They are commonly used for fine-tuning, calibration, and signal adjustment in portable electronics, medical devices, and instrumentation where space-saving and reliable performance are essential.

Our Strengths

Every Solution Starts With Your Problems

Price Too High, Budget Under Pressure

You don’t have to pay extra for the same specifications. We help you reduce costs while fully meeting your standards.

Original Models Discontinued, Hard to Find Replacements

Obsolete models don’t mean you have to scrap your equipment. We custom-make replacement parts for discontinued models.

Lead Time Too Long, Project Falling Behind

Every week counts—delays are not an option. Our standard production lead time is just 45 days.

Big Brands Ignore Small Orders Or Minor Tweaks

Small orders and minor adjustments matter, too. We handle custom tweaks and low-volume runs with fast turnaround.

Worried About Unreliable Quality From China Factory

You need proven reliability, not just paper specs. All our products come with real factory test reports.

Only Quoting, No Product Expertise

You don’t just want a price—you want someone who truly understands your needs. We clarify your requirements before quoting, drawing on years of experience.

How does it work

How sensors and potentiometers turn movement into precision control across diverse industries.

frequently asked questions

About ordering

→ 30 Days Sample | 45 Days Mass Production

The minimum order quantity (MOQ) is 10 units.

A setup charge typically covers additional expenses related to customizing standard components or performing special operations requested by customers. These charges depend entirely on the complexity of the modifications, are design-specific, and usually apply to each order separately.

The Low Volume Charge (LVC) helps to clearly identify these fixed costs, ensuring transparency when ordering smaller quantities. This charge accounts for the higher proportion of fixed manufacturing expenses inherent in low-volume production runs.

Potentiometer Performance

We manufacture Conductive plastic ourselves and strictly control the processing flow to ensure the electrical performance of the resistor components.

Yes, we can provide mass production of replacement-type potentiometers and other related components.

Yes, we can customize and produce products such as angle sensors and linear sensors.
