Technical Frequently Asked Questions

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

The order code has six fields: mechanical version, digital interface, resolution, interface, parameters, and connection. For example, RFC-4802-214-831-302 is the version with round hole mounting, digital interface, 14 bits, SPI with Ub = 5 VDC, binary code and clockwise increasing characteristic, and a 1 m shielded 5-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 SPI contactless angle sensor operate?

Operating temperature: -40 … +85 °C. Protection: IP67 / IP68 / IP69.
