Which M12 code type should be selected for encoder signals of servo motors?

Q: Which M12 code type should be selected for encoder signals of servo motors?

A: Choose the M12 A-code (4Pin/5Pin). It supports the RS485 bus with a transmission rate of 100Mbps and a contact resistance of <3mΩ, ensuring the accurate transmission of encoder angle signals (±0.001°) and meeting the high-frequency response requirement (≤1ms) of servo systems. For absolute encoders, select the 5Pin version, which additionally transmits zero-position signals.
