Multi-Turn Magnetic Absolute Encoders

Bulletin 842A Multi-Turn Magnetic Encoder is a 25-bit absolute multi-turn shaft encoder. It provides up to 8192 pulses per turn or a maximum of 8192 turns. It uses a technology called Synchronous Serial Interface (SSI) to provide 24-bit resolution over just 5 wires. The SSI output from the 842A encoder can be interfaced in several different ways.
