Cable assembly for ECOFAST distribution
The Siemens 3RK1911-0BD20 is a pre-terminated ECOFAST power connection line for distributing motor and sensor power in AS-Interface and SIMATIC ET 200pro installations. Seven conductors of 2.5 mm² each, 3 m long, with a HAN Q8/0 connector factory-fitted on one end. The opposite end is unterminated — you land the bare wires in the control cabinet or a junction box. Lifecycle stage is current, so this is an active catalog line with no phase-out notice.
The 7 x 2.5 mm² conductor bundle carries the power and signal pairs typical of an ECOFAST trunk. 2.5 mm² is sized for the branch-circuit ampacity of a standard AS-i power supply or a 24 VDC distribution block — enough for a group of sensors and actuators within a 3 m reach. The HAN Q8/0 connector on one side mates directly to ECOFAST receptacles on the field module; the unterminated tail feeds into the cabinet. This is a point-to-point cable, not a loop-through; order one per drop.
No successor or replacement part is published. Sourcing is standard — quoted to order through the Siemens industrial automation channel. For BOM freeze or PCN watch, the current status means no imminent LTB trigger, but always confirm the latest lifecycle status before a long production run.
