Technical Frequently Asked Questions

What can be connected to the RFC-4800 incremental angle sensor?

It can be connected to Novotechnik M12 connectors and cables and Novotechnik rotary sensor positioners (magnets).

How do I order the RFC-4800 incremental angle sensor?

The order code has six fields: mechanical version, digital interface, resolution, interface, parameters, and connection. For example, RFC-4802-212-535-432 is the version with round-hole mounting, digital interface, 1024 ppr (4096 counts), incremental A/B/Z in low-speed mode, Ub = 24 VDC, TTL-compatible RS-422 output, and a 1 m shielded 8-pole cable. All the options for each field are available in the order code configurator on this page.

Under what conditions does the RFC-4800 incremental angle sensor operate?

Operating temperature: -25 … +85 °C (M12 connector), -40 … +85 °C. Protection: IP67 / IP68 / IP69 (M12 connector: IP67).
