The 6ES7923-5CB00-0CB0 is a pre-assembled round cable for the SIMATIC S7-1500 system, designed to connect the front connector module to the connection module on a 50-pin interface. It carries 50 conductors at 0.14 mm² each, terminated with IDC connectors at both ends, and runs 10 m between the two points. The cable is unshielded and transmits digital signals only — it is not rated for analog signal paths.
Rated voltage and operating range
The cable is rated at 24 V nominal, with a maximum voltage of 60 V. That means it is sized for the 24 VDC digital I/O bus common on S7-1500 modules, and the 60 V ceiling gives headroom for transient spikes without derating. Operating temperature range is 0 to 60 °C during use; storage range extends from -30 to +70 °C.
Construction and handling
Round cable, black PVC sheath, 10.3 mm outer diameter. The 50-pole IDC connectors mate to the cable-side front connector module at one end and the connection module at the other. Field connection and enclosure connection both use connector strips — no screw terminals, no soldering. Conductor cross-section is 0.14 mm², fine enough to fit the IDC slots but not for high-current wiring; this is a signal cable, not a power cable.
