The Siemens 6ES7923-5BC00-0DB0 is a pre-assembled shielded round cable purpose-built for SIMATIC S7-1500 systems. It connects a 50-pin front connector module on the I/O card side to a 50-pin connection module in the field, using IDC connectors at both ends. The 2 m length and 0.14 mm² conductors suit cabinet wiring runs where you need a fixed, factory-terminated harness rather than field-stripped individual wires. Rated at 24 V with a maximum of 60 V, this cable handles both digital and analog signal transmission — the braided shield keeps common-mode noise off sensitive analog inputs. The 32-channel capacity matches the typical channel count of S7-1500 digital and analog I/O modules, so one cable per module is the standard fit.
Physical fit and wiring notes
The cable is round, black PVC-sheathed, with an 11 mm outer diameter. The braided shield terminates into the IDC connector housing at both ends — no separate shield clamp needed. The 50-pin IDC connector on the cable side mates directly to the S7-1500 front connector module (e.g., 6ES7592-1AM00-0XB0); the field-side 50-pin connector strip lands on the connection module. Strip length and pinout are factory-set, so no field termination is required. The PVC jacket is rated for fixed installation inside enclosures — not for continuous flexing or cable-track duty.
