842A Multi-Turn Magnetic
The 842A multi-turn magnetic encoder is a 25-bit absolute multi-turn shaft encoder. Provides up to 8192 pulses per turn, or up to 8192 turns. It uses a technology called Synchronous Serial Interface (SSI) to provide 24-bit resolution over just 5 wires. The synchronous serial interface outputs of the 842A encoder can be connected in a number of different ways.
• Reduced wiring cost and complexity
• Noise immunity through differential communication format
• Startup is simplified
• Choice of Gray code or natural binary format
