Specialized Potentiometer Supplier with In-House Manufacturing and Custom Engineering
Spec confirmation → sample validation → small-batch scale-up/delivery
Typical sample lead time: ~25 days
We are a mid-sized manufacturing team. We provide custom and replacement potentiometer elements and potentiometer sensors for overseas customers.
Your custom project is not limited by one factory’s processes or product range. You gain access to our in-house capabilities and qualified production partners to develop the right potentiometer solution.
Started with wirewound potentiometers and extended to multi-turn long-life structures (up to 20 turns) for finer adjustment and stable long-term use.
Built thick-film circuits and a stable wiper contact system to improve consistency in mass production, with TPS-style structures as a typical example.
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.
Expanded into multi-gang and stackable designs, plus special builds for small-batch, multi-variant supply where mechanical interfaces and channel consistency matter.
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.

Potentiometer housing costs depend on much more than the price of the raw material. This article compares machined metal, stamped metal, injection-molded plastic, Bakelite, ceramic, and fiberglass housings, based on what we learned from several small-batch replacement projects.
A manufacturer’s discussion of carbon film, conductive plastic and cermet resistive elements for audio potentiometers and faders, focusing on taper, sliding noise, service life, surface roughness and precious-metal wiper contact.
For miniature drones, robots, and actuators, a 6 mm contact-type angle sensor looks very attractive. But when we look inside the sensor, the real limitations become clear: resistive track width, linearity trimming space, precious metal wiper width, lifetime, and tooling cost. This article explains why high-performance contact-type angle sensors are usually larger than 10 mm, and why 15 mm is often more realistic for conductive plastic designs.
Many small contact-type components look similar, especially trimmers, miniature potentiometers, and miniature angle sensors. For drone, robot, and prototype design, this confusion can lead to the wrong space reservation and poor angle feedback performance. This article explains why the final sensor selection should focus on usable electrical angle, resistive track space, wiper contact, output stability, and realistic manufacturing limits.
A string potentiometer and a linear potentiometer position sensor can both measure linear movement, but their internal structures are different. This article explains how string movement is converted into rotary feedback, why linear sensors need a straight resistive track, and what manufacturing challenges appear in compact string potentiometers such as the TE M150.
Based on a real 15 mm OD project, this article explains why small-diameter conductive plastic resistive elements are harder to push to a larger effective electrical angle, and what structure changes may help.
