Custom & Replacement High-Performance Potentiometers

We are a China manufacturer, serving overseas customers and export projects.

Spec confirmation → sample validation → small-batch scale-up/delivery

Typical sample lead time: ~25 days

Brands We Worked With

About NOL.

We are a mid-sized manufacturing team. We provide custom and replacement potentiometer elements and potentiometer sensors for overseas customers.
For replacement projects, we do more than match the appearance. We focus on key electrical specs and critical mechanical interfaces. We confirm specs first, issue a spec confirmation document, then validate by samples.

What We Make, and How It Evolved

2003~ Wirewound → Multi-turn long-life

Started with wirewound potentiometers and extended to multi-turn long-life structures (up to 20 turns) for finer adjustment and stable long-term use.

2011~ Thick-film circuit & wiper (TPS as example)

Built thick-film circuits and a stable wiper contact system to improve consistency in mass production, with TPS-style structures as a typical example.

2015~ Conductive Plastic Elements & Precious-Metal Wiper

Introduced conductive-plastic resistive elements with precious-metal spring contacts. In selected designs, TCR can be as low as ±150 ppm/°C, supporting MIL-grade replacement needs.

2018~ Multi-gang / stackable / special builds

Expanded into multi-gang and stackable designs, plus special builds for small-batch, multi-variant supply where mechanical interfaces and channel consistency matter.

2021~ High-performance carbon film (360 degree )

Developed high-performance carbon-film solutions (life up to 5 million cycles), offering a larger effective electrical angle and a more cost-controlled manufacturing process.

How We Confirm Fit and Move to Production

Start with your specs. End with stable deliveries.

Who We Support

• New tooling & custom builds;
• Replacement / upgrade (cost-down included);
• Discontinued part replication;
• Small-batch, multi-variant supply.

How We Confirm Fit

• Conditions: temp, vibration, sealing, media;
• Materials: CP / carbon / wirewound + wiper;
• Targets: life, linearity, TCR, torque, resistance;
• Interfaces: mounting, shaft, angle/stroke, stops.

How We Move to Production

• Input: drawings/datasheet, or photos with key dimensions (email attachment or link);
• Feasibility: material route and risk notes;
• Sample test: confirm dimensions, electrical behavior, and assembly fit;
• Small batch: first-article check + in-process checks;
• Batch delivery: delivery by batches with traceability (if applicable).
