The Siemens 6ES7923-0BG50-0CB0 is a pre-assembled unshielded round cable that links the front connector module to the connection module on SIMATIC S7-300 and S7-1500 systems. It carries 16 poles across 8 channels, sized for digital I/O modules with a rated voltage of 24 V and a maximum of 60 V.
The cable is terminated with IDC connectors at both ends — 16 poles at the first interface (cable-side front connector module) and 16 poles at the second interface (connection module). The 6.5 m length gives routing slack inside a cabinet between the I/O rack and the field-side connection block without needing a junction box. Each conductor is 0.14 mm², PVC-sheathed, with an outer diameter of 6.5 mm. The black jacket holds up to storage temperatures from -30 °C to +70 °C and operating temperatures from 0 °C to 60 °C — fine for climate-controlled control rooms but not for unheated freezer environments.
The product status is active, so it remains a standard catalog item through Siemens distribution. No phase-out or last-time-buy window is in effect.
