The Siemens 3RK1911-0CP32 is an ECOFAST spur cable — 5 x 6 mm², 3m to 5m, preassembled at both ends with HAN Q4/2 connectors. This is the drop cable that connects a field device (sensor, actuator, or I/O block) back to the ECOFAST trunk line in a modular wiring system, eliminating field-wiring terminations and reducing installation time on automated lines.
No substitute or second-source cross-reference exists in the evidence.
Deployment context
The ECOFAST system is a pre-wired, modular distribution architecture used in automotive, material handling, and machine-build lines where multiple sensors and actuators are daisy-chained from a trunk cable. This spur cable carries the 5 x 6 mm² conductors needed for power and signal to a single device drop, with HAN Q4/2 connectors that mate directly to the device or a junction box.
