The Siemens 6ES7923-0BE00-0CB0 is a pre-assembled round cable designed to connect SIMATIC S7-300 and S7-1500 front connector modules to a connection module. It is unshielded, 4 m long, and terminates in IDC connectors on both ends, with 16 poles and 16 conductors of 0.14 mm² cross-section. The cable sheath is black PVC with a 6.5 mm outer diameter. Rated for 24 V operation with a maximum voltage of 60 V, this cable is specified for digital signal transmission only — it is not suitable for analog signals. It carries 8 channels and is intended for use with digital I/O modules. The operating temperature range is 0 to 60 °C, with storage from -30 to +70 °C. The cable uses a connector strip type of electrical connection both in the field and on the enclosure.
