The Siemens 6ES7923-0BB00-0FB0 is a universal connecting cable from the SIMATIC S7 family, designed to bridge an I/O module to a control system without needing a custom harness. One end terminates in an unshielded IDC connector that mates directly to 8 I/O connection modules; the other end is stripped to open wires with end sleeves, ready for termination on a terminal block or screw connector in the control cabinet. The cable is labeled along its length for easy identification during commissioning.
The 1.0 m length and 0.14 mm² conductor cross-section tell you this is a signal-level cable, not a power feeder. It carries the 8 I/O channels from a connection module to the control system's termination point — think digital inputs from proximity sensors or digital outputs to indicator lamps. The unshielded construction means it is suitable for clean electrical environments inside a steel enclosure; keep it away from VFD output cables or high-frequency noise sources. If your run needs to pass through an EMI-heavy zone, you would reach for the shielded variant in this family instead. The IDC connector on one side and open ends on the other make this a field-termination cable: you plug the IDC into the I/O module, then land the open wires on your control system's terminal strip. The end sleeves (wire ferrules) are already fitted, so no crimping is needed on that end — just strip the cable jacket, insert, and tighten. The labeling along the cable saves a step during panel wiring; you can trace each conductor back to its module channel without a toner.
