Client Profile: A mid-sized German industrial automation equipment manufacturer specializing in precision motor drives and servo control systems for European manufacturing plants.
The client's servo drive calibration circuit required a precision voltage reference adjustment component with stringent specifications: temperature drift below ±50ppm/°C, mechanical vibration resistance for factory-floor environments, and consistent linearity across the full 10-turn adjustment range. Previously sourced wire-wound potentiometers from a Japanese supplier had experienced 8-week lead times and increasing minimum order quantities, threatening production schedules.
Sichuan Qixing Electronics recommended the BONENS 3590 multi-turn wire-wound potentiometer for its combination of low temperature coefficient, robust mechanical construction, and proven vibration resistance. Engineering samples were delivered within 48 hours with full test documentation, enabling rapid design validation. The 3590's multi-turn configuration provided the fine adjustment resolution necessary for precision voltage calibration.
| Metric | Before (Previous Supplier) | After (BONENS 3590) |
|---|---|---|
| Calibration Accuracy | ±1.0% | ±0.5% |
| Lead Time | 8 weeks | 3 weeks |
| Unit Cost | Baseline | -22% |
| Field Failure Rate (12mo) | 0.8% | 0.3% |
The client transitioned 100% of its wire-wound potentiometer procurement to BONENS 3590 series, achieving both performance improvement and cost reduction. The enhanced calibration accuracy directly contributed to improved servo drive positioning precision, a key competitive differentiator in their market.
