Technical Frequently Asked Questions
What can be connected to the RFC-4800 SSI contactless angle sensor?
Se le pueden conectar conectores y cables M12 de Novotechnik y posicionadores (imanes) para sensores rotativos de Novotechnik.
How do I order the RFC-4800 SSI contactless angle sensor?
The order code has six fields: mechanical version, digital interface, resolution, interface, parameters, and connection. For example, RFC-4802-212-441-432 is the version with round hole mounting, digital interface, 12 bits, SSI with Ub = 24 VDC and clockwise rising characteristic, 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 SSI contactless angle sensor operate?
Operating temperature: -25 … +85 °C (M12 connector), -40 … +85 °C. Protection: IP67 (M12 connector), IP67 / IP68 / IP69.
