Specification
Key Product Features
- Hollow Shaft Compact DesignThe 28mm hollow structure allows easy wiring and installation through the central shaft, saving internal device space while supporting custom knob mounting. The lightweight modular body fits seamlessly into slim product designs without compromising structural stability.
- High Precision & Durable PerformanceWith up to 24/30 detent positions and 360° infinite rotation, the encoder provides accurate position sensing with minimal jitter. The gold-plated contact points ensure over 30,000 rotation cycles, maintaining stable signal output even after long-term frequent operation.
- Tunable Tactile FeedbackWe offer multiple torque options ranging from 15gf.cm to 50gf.cm, delivering crisp, consistent clicking feedback for users. This customizable hand-feel greatly enhances the operational experience compared to traditional push-button switches.
- Multiple Output & Interface OptionsSupporting standard incremental AB phase output, with optional push-button integration (press-to-select function), the module is compatible with 3.3V/5V mainboard systems. It works perfectly with common MCU platforms without extra signal conversion circuits.
- Strong Environmental AdaptabilityThe industrial-grade plastic housing and sealed contact structure protect the encoder from dust, minor splashes, and temperature fluctuations. It reliably operates across -20°C to +70°C, fitting both indoor and semi-outdoor smart device scenarios.
- Factory Direct Customization ServiceAs the original manufacturer, we provide full OEM support: custom shaft length, pin definition, output pulse number, and connector types. Short lead times for bulk orders and dedicated technical support help reduce your overall procurement cost.
