The core components of the product achieve 100% domestic production, ensuring a stable and reliable supply chain and exceptional quality.
Utilizing high-precision magnetic induction technology, we provide single-turn and multi-turn encoder solutions.
Supports Profibus-DP bus to enable high-speed, stable data communication in industrial field applications.
Single-turn resolution reaches up to 16 bits, while multi-turn resolution achieves 14 bits, meeting high-precision measurement requirements.
Featuring exceptional impact and vibration resistance, with a protection rating up to IP66, it is designed to withstand harsh environments.
Built-in reverse-shorting and short-circuit protection effectively minimizes the impact of installation errors on the encoder.

Wiring Definitions
| Signal | Definition |
|---|---|
| ⊥ | Power cord ground wire |
| B (left) | Data Cable B (Pair 1), Incoming Line |
| A (left) | Data Line A (Pair 1), Incoming Line |
| (-) | 0V |
| (+) | 10V…30V |
| B (right) | Data Cable B (Pair 2), Output Cable |
| A (right) | Data Line A (Pair 2), Outgoing Cable |
| (-) | 0V |
| (+) | 10V…30V |
| Notes | The power supply only needs to be connected once (regardless of which terminal group is used); when the terminal resistor is engaged, the BUS OUT is disconnected. |
Indicator Lights and How They Work
LED indicator
| LED red | LED green | Status Information/Possible Causes |
|---|---|---|
| 暗 | 暗 | No power supply |
| 亮 | 亮 | The rotary encoder is ready for operation but has not yet received voltage-based configuration data. Possible causes: incorrect address settings, incorrect bus connections, etc. |
| 亮 | 闪 | Parameter assignment or configuration error. The length of the configuration or parameter assignment data received by the rotary encoder is likely incorrect or the data is inconsistent. Possible cause: e.g., total resolution set too high. |
| 闪 | 亮 | The rotary encoder is ready for operation but has not been accessed by the master station (e.g., due to an incorrect address). |
| 亮 | 暗 | The rotary encoder has not received any data within a certain period of time (approximately 40 seconds) (the data line may be disconnected). |
| 暗 | 亮 | Data exchange operates in normal mode. |
| 暗 | 闪 | Data exchange operates in debug mode. |
