The Siemens 6ES7923-5BJ00-0CB0 is a pre-assembled round cable purpose-built for SIMATIC S7-1500 systems, linking the front connector module to the connection module on digital I/O racks. It carries 50 conductors at 0.14 mm² each, terminated with IDC connectors at both ends, and runs 8 m between the two points. Rated at 24 V with a maximum of 60 V, it handles the signal-level voltages typical of S7-1500 digital input and output cards without analog signal transmission.
Integration notes
The 50-pole IDC connector on the cable side mates with the front connector module of an S7-1500 digital I/O module (32-channel typical), while the second 50-pole IDC lands on the connection module at the cabinet wiring interface. The round PVC-sheathed cable, 10.3 mm outer diameter in black, routes through standard cable ducts or along DIN-rail profiles. Operating temperature range is 0 to 60 °C; storage from -30 to +70 °C. No analog signal capability — this is a pure digital-signal path.
