It is unshielded, 2 m long, and uses IDC connectors at both ends, carrying 16 conductors with a cross-section of 0.14 mm² each. Rated for 24 V and tested to a maximum of 60 V, it is designed specifically for digital I/O modules — not for analog signal transmission. The 24 V rated value matches the standard control voltage on S7-300/1500 backplanes and digital I/O modules. The 60 V maximum is the insulation rating — the cable can handle signal peaks or short-term overvoltage without breakdown, but it is not a power cable. The 2 m length is fixed; there is no field-cut option because the IDC connectors are factory-terminated. The 16-pole, 8-channel configuration means one cable serves one 8-channel digital I/O module, with each conductor carrying a single digital signal (24 V sensor/actuator or PLC output). ## Deployment context This cable runs between the front connector on an S7-300/1500 I/O module and a separate connection module mounted in the same enclosure. The round, black PVC sheath (6.5 mm outer diameter) is flexible enough for routing in a control cabinet but unshielded, so keep it away from variable-frequency drive output cables or other high-noise sources.","metaTitle":"Siemens 6ES7923-0BC00-0CB0 Pre-assembled Cable, 2m, 16-Pin I","metaDescription":"Siemens 6ES7923-0BC00-0CB0 pre-assembled round cable for SIMATIC S7-300/1500. 16-pin IDC connector, 2m length, rated 24V, max 60V.
