It carries 50 conductors of 0.14 mm², terminated with IDC connectors at both ends, and runs 10 m between the two interfaces. Rated at 24 V with a maximum of 60 V, this cable is suited for the 24 VDC control signals typical of S7-1500 digital and analog I/O modules — the 60 V ceiling gives headroom for signal transients without risk of breakdown across the 0.14 mm² conductors. With 32 channels over 50 poles, it handles a full 32-point I/O module in one harness, keeping the wireway organized and reducing point-to-point wiring errors during panel build. ## Deployment context: panel integration The braided shield (11 mm outer diameter, PVC sheath) means this cable is intended for environments where electrical noise from drives or contactors could corrupt 24 VDC signals — the shield ties to ground at the module end, protecting analog signal integrity on the same harness. Operating range of 0 to 60 °C covers most control cabinet interiors; storage range of -30 to +70 °C allows for unheated warehouse staging before installation. The round cable design with a connector strip at both ends means it snakes through standard cable ducts and gland plates without the stiffness of a ribbon cable — useful when the remote connection module sits in a different zone of the panel.","metaTitle":"Siemens 6ES7923-5CB00-0DB0 Pre-assembled Cable, 10 m, for S7","metaDescription":"Siemens 6ES7923-5CB00-0DB0 pre-assembled shielded round cable, 10 m, 50-pin IDC, for SIMATIC S7-1500 I/O modules.
