Technical Frequently Asked Questions
What can be connected to the RFC-4800 CANopen 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 CANopen contactless angle sensor?
The order code has 7 fields: mechanical version, digital interface, resolution, interface, parameters, speed, and connection. For example, RFC-4852-214-614-432 is the version with round hole mounting, digital interface, 14 bits, CANopen with 1 position and 1 speed (one channel), 250 kBaud, and a 1 m shielded 8-pole cable (CAN input/output). All the options for each field are available in the order code configurator on this page.
Under what conditions does the RFC-4800 CANopen contactless angle sensor operate?
Operating temperature: -40 … +105 °C, -25 … +85 °C (M12 connector). Protection: IP67 / IP68 / IP69, IP67 (M12 connector).
