It runs 50 conductors between a 16-pole front connector module on the module side and a 50-pole connection module on the field side, using IDC connectors at both ends. The 2.5 m length and 0.14 mm² conductor cross-section are fixed — no field termination or cutting to length. Rated at 24 V for signal levels, with a maximum voltage of 60 V. The 50-pole connection at the field side and 16-pole interface at the module side mean this cable handles 32 digital channels in a single harness — one 50-pin connector breaks out into four 16-pin front connectors. The 0.14 mm² conductor is sized for signal-level current on digital inputs or outputs, not power wiring. The 2.5 m reach fits standard cabinet depths between the I/O rack and a terminal block row; if your panel layout exceeds that, you need a different order code. The PVC sheath (10.3 mm outer diameter) is unshielded, so keep it away from variable-frequency drive or motor cables to avoid coupled noise.","metaTitle":"Siemens 6ES7923-5BC50-0EB0 Pre-assembled Cable, 50-pin, 2.5","metaDescription":"Siemens 6ES7923-5BC50-0EB0 pre-assembled round cable for SIMATIC S7-300/1500 digital I/O. 50-pin IDC, 2.5 m, 24 V rated, 60 V max.
