Technical Frequently Asked Questions

What can be connected to the SSI RMB-3600 magnetic absolute encoder?

It can be connected to Novotechnik M12 connectors and cables and Novotechnik rotary sensor couplings and accessories.

How do I order the RMB-3600 SSI magnetic absolute encoder?

The order code has six fields: mechanical version, interface, revolutions, parameters, and connection. For example, RMB-3601-214-441-FM8 is the synchronous flange version with a 6 mm x 12.5 mm shaft, digital interface, 14 revolutions (5040°), 16-bit clockwise increasing Gray code SSI, and an 8-pin M12x1 connector. All the options for each field are available in the order code configurator on this page.

Under what conditions does the SSI RMB-3600 absolute magnetic encoder operate?

Operating temperature: -30 … +85 °C (connector), -40 … +85 °C (cable); higher temperatures available upon request.
