EnDat 3 is the latest release of this proven interface with features such as hybrid cabling, bus topology, functional safety (black channel communication) and multi-sensor support enabling HEIDENHAIN encoders to be fully integrated within a digital manufacturing environment.

HMC 2 is a single cable solution for motors where encoder power and data can be transmitted using only two wires saving on weight, reducing cable size and the number of connectors required ultimately improving reliability and reducing cost. Other applications using EnDat 3 feature our MRS series encoder modules designed for robot arm joints. The encoders can be configured in bus operation mode and as well as transmitting position information can report temperature to the control electronics to enable thermal compensation.
