The second data pair provides data and the peripheral voltage (Up) for the supply of the actuators. This direct coupling of the supply voltage to the 100 MBit line for EtherCAT-P enables a compact and cost-effective device interface.
Since the supply lines are no longer required, this is referred to as a "one cable solution".
In order to make it impossible to connect with other standardized M8x1 connector systems, a new coding has been developed for this application and standardized in IEC 60176-2-114 under the term
"P - Coding". Special features of this coding are the red colouring of the contact carriers and the leading T-contour on the front face of the coupling contact carrier, which prevents connecting with other codings.
Connectors overmoulded:
Currently, shielded axial overmoulded designs with cable quality G6, TPU 4xAWG22, are available in the standard lengths. For the 100 MBit device connection almost exclusively male-male patch cords are used.
Connectors field attachable:
Field attachable connectors are available as female and male variants in axial design, either with screw (Female and Male connector) or crimp (male connector) termination.
Flanges for direct PCB mounting:
An extensive product range for device connection is available here, so that the user has many variable installation options. The continuous shielding from the flange housing to the circuit board is realised with a punched sheet metal plate. Moulded contact tongues form the radial connection to the flange housing, the connection to the printed circuit board is made by means of latching elements with subsequent soldering. The materials used are suitable for wave soldering. A special flange version is the version with moulded cable and a further plug on side B, preferably P-coded. Ideally, this can be used for wiring through a wall, e. g. a switch cabinet.
