The EL9181 potential distribution terminal provides two potentials with 8 terminal points each for potential distribution and enables the tapping of the voltages without further terminal blocks or wiring work. The power contacts are fed through to the next terminal without connecting to the terminal points.

The HD EtherCAT Terminals (high density) with increased packing density contain 16 connection points in the housing of a 12 mm-wide EtherCAT Terminal. Solid wire conductors can be connected without tools using the direct plug-in technique.
