Functional Features:
- 17-bit resolution — 131,072 positions per revolution
- BiSS-C protocol — supports daisy-chain, diagnostics, and parameterization
- Higher speed rating — up to 10,000 RPM (vs. 8000 RPM on S700)
- Enhanced diagnostics — real-time temperature and voltage monitoring
- Improved EMC performance over S700 series
Structural Characteristics:
- Ø58 mm cylindrical housing
- Upgraded precision bearing system for 10,000 RPM
- Enhanced sealing for IP67 in harsh environments
- M23 12-pin connector
Working Principle:
Identical to S700 series — LED illuminates a 17-bit glass code disk. Photodetectors read the absolute position. BiSS-C protocol transmits position and diagnostic data bidirectionally over a single differential pair.
Key Advantages:
- 10,000 RPM rating — suitable for high-speed spindle applications
- 17-bit resolution — four times the resolution of S700 base models
- BiSS-C diagnostics — predictive maintenance capability
- Drop-in compatible with S700 mechanical mounting
Applicable Industries:
- High-speed spindles
- Semiconductor wafer handling
- Printing press rollers
- Textile high-speed machinery
- Robotics high-speed joints
Installation Requirements:
- Same mechanical mounting as S700 series
- BiSS-C compatible drive required
- Shielded twisted pair cable, max 100 m
Usage Precautions:
- Do not exceed 10,000 RPM
- Verify BiSS-C termination in daisy-chain configuration
- Maintain IP67 seal integrity
