CHENGDU, China – August 2026 – Sichuan Qixing Electronics Co., Ltd. unveils its flagship BONENS multi-turn wire-wound potentiometer series — models 3590, 3540, and 534 — purpose-built for precision voltage calibration, industrial servo drives, laboratory instrumentation, and high-reliability test & measurement equipment.
3590 Series: The Heavy-Duty Workhorse
The BONENS 3590 multi-turn wire-wound potentiometer delivers exceptional linear accuracy with minimal temperature drift. Featuring a robust wire-wound resistance element and wide resistance range, it excels in high-power precision voltage calibration and industrial drive applications where load stability and vibration resistance are non-negotiable. Target markets: European, North American, and Southeast Asian industrial equipment manufacturers.
3540 Series: Compact Multi-Turn Precision
Engineered for PCB-mounted applications, the 3540 series offers 10-turn adjustment capability in a standard compact package. With excellent temperature stability and multiple resistance options, it is the go-to choice for servo control systems, EV charging station control boards, and automated test equipment. Target markets: Global industrial automation and new energy sectors.
534 Series: Miniature Precision for Sensitive Instruments
The 534 miniature multi-turn wire-wound potentiometer combines ultra-compact packaging with low contact resistance and superior linearity. Designed for space-constrained precision instruments, sensor modules, and laboratory equipment, it maintains stable performance over extended operational life. Target markets: North American and European precision equipment manufacturers, medical device integrators.
Manufacturing Excellence
All three series are produced in Sichuan Qixing's ISO9001:2015 certified facility, with rigorous multi-point testing at every production stage. The wire-wound elements undergo specialized thermal cycling and load testing to ensure consistent performance across operating temperature ranges.
